What are the risks of stem cell therapy?The risks depend on the treatment. After a donor-cell (allogeneic) transplant, graft-versus-host disease occurs in about 35–45% of patients with related donors and 60–80% with unrelated donors. Infections are another serious risk. With unapproved products, the FDA has reported blindness, tumor formation, sepsis, neurological events, unwanted immune reactions and cells moving to unintended sites.Stem Cell Treatment · informational · 10 sources · Verified Sep 18, 2026How do I know if a stem cell clinic is legitimate?Ask for published preclinical studies that independent experts have reviewed, approval from an ethics review board, and authorization from a national regulator such as the FDA, EMA or MFDS. Also ask for a written protocol and a consent form. The ISSCR lists these warning signs: testimonial-based claims, one treatment for many unrelated diseases, an unclear cell source, claims of no risk, and high or hidden costs.Stem Cell Treatment · provider · 10 sources · Verified Sep 18, 2026Is stem cell therapy legal in South Korea?Yes, within limits. The Ministry of Food and Drug Safety has approved several stem cell products, including Cellgram-AMI, Cartistem, Cupistem and Neuronata-R. Since a February 2025 amendment to Korea's advanced regenerative medicine law, designated institutions may also offer investigational cell therapies to patients with life-threatening, intractable or rare diseases. Each treatment plan needs approval from a central committee, and patients pay the full cost.Stem Cell Treatment · informational · 10 sources · Verified Sep 18, 2026What is the difference between adult stem cells and embryonic stem cells?The main difference is potency. Embryonic stem cells are pluripotent and can give rise to nearly all of the body's cell types. Adult stem cells are generally multipotent or unipotent, so they make only the cell types of their own tissue. Adult stem cells come from mature tissues such as bone marrow, skin or the cornea. Blood stem cell transplantation, which uses adult stem cells, is an established therapy.SVF & Adipose-derived Cells · informational · 12 sources · Verified Sep 18, 2026Where are adult stem cells found in the body?Adult stem cells are found in many organs, including bone marrow, skin, gut, skeletal muscle, brain and the rim of the cornea. Mesenchymal stromal cells can also be isolated from fat tissue, umbilical cord Wharton's jelly and dental pulp. The cells usually sit in a specialised microenvironment, or niche, which controls when they divide and when they produce mature cells.SVF & Adipose-derived Cells · informational · 12 sources · Verified Sep 18, 2026What diseases are treated with adult stem cells?The established use is hematopoietic stem cell transplantation for blood cancers such as leukaemia, lymphoma and myeloma, and for some bone marrow and immune disorders. Skin grafts and corneal stem cell grafts for eye burns are also recognised. A bone-marrow-derived MSC product is approved in the US for steroid-refractory acute graft-versus-host disease in children. Most other claimed uses are unproven.SVF & Adipose-derived Cells · informational · 12 sources · Verified Sep 18, 2026Are mesenchymal stem cell treatments FDA approved?Only for a narrow use. In December 2024, the FDA approved remestemcel-L-rknd (Ryoncil), an MSC product made from donor bone marrow, for steroid-refractory acute graft-versus-host disease in patients aged 2 months and older. It was the first FDA-approved MSC therapy. No stem cell product is FDA-approved for orthopaedic conditions such as knee arthritis or back pain, or for neurological diseases, autism or anti-aging.SVF & Adipose-derived Cells · informational · 12 sources · Verified Sep 18, 2026What is the difference between white fat and brown fat?White fat cells hold one large lipid droplet, which fills about 90% of the cell, and mainly store energy as triglycerides. Brown fat cells hold many small droplets and many mitochondria. They use uncoupling protein 1 (UCP1) to burn energy as heat without shivering. In adults, brown fat is found mainly in the neck, above the collarbones, along the spine and in the centre of the chest. White fat is found under the skin and around the organs.SVF & Adipose-derived Cells · informational · 10 sources · Verified Sep 18, 2026Why is visceral fat more dangerous than subcutaneous fat?Visceral fat lies deep in the abdomen and wraps around internal organs. Excess visceral fat is linked to cardiovascular disease, type 2 diabetes, high cholesterol and atherosclerosis more closely than fat under the skin. One clinical source estimates it normally makes up about 10% of total body fat. A waist of 35 inches or more in women, or 40 inches or more in men, is commonly used as a sign of higher risk.SVF & Adipose-derived Cells · informational · 10 sources · Verified Sep 18, 2026Do fat cells disappear when you lose weight?Mostly not. A 2008 Nature study that dated fat cells with carbon-14 found that the number of fat cells stays roughly stable in adulthood, with no significant rise between ages 20 and 70. Weight change mainly reflects fat cells getting bigger or smaller. Individual fat cells are still replaced over time, at an estimated rate of about 8.4% per year, so roughly half are renewed every 8.3 years.SVF & Adipose-derived Cells · informational · 10 sources · Verified Sep 18, 2026Why is fat tissue used as a source of stem cells?Fat is plentiful and easy to collect by liposuction. A single procedure can produce from 100 ml to more than 3 litres of lipoaspirate. Breaking down this tissue releases the stromal vascular fraction (SVF), a mix of cells in which stem cells make up only about 2–10%. In the United States, the FDA lists fat-derived SVF among regenerative products marketed without approval, and it has received reports of serious harms linked to unapproved products.SVF & Adipose-derived Cells · informational · 10 sources · Verified Sep 18, 2026Can your body reject your own fat after a fat transfer?No, not in the immune sense. Autologous fat comes from the same person, so it carries no risk of immune rejection and no allergy or viral-transmission concerns. Some of the graft is still usually lost, because transferred fat has no blood supply at first and fat cells far from nearby tissue can die before new vessels form. Reviews report resorption of 25% to 80%, depending on technique and the recipient site.Autologous Fat Grafting · informational · 10 sources · Verified Sep 18, 2026How much transferred autologous fat survives?The amount varies widely. One review gives a resorption range of 25% to 80%, and another reports survival of 50–90% even among experienced surgeons. A 2026 systematic review of fat transfer to the breast found pooled mean survival of about 56% for abdominal fat at 12 months. The figures depend on how volume is measured, the recipient site, the technique and the length of follow-up, so any single percentage is only a rough guide.Autologous Fat Grafting · informational · 10 sources · Verified Sep 18, 2026Which body area is best for harvesting fat for grafting?No donor site has been clearly shown to be best. The lower abdomen and inner thigh have been reported to contain more adipose-derived stem cells. A 2026 systematic review found higher pooled survival for abdominal fat than for thigh fat in breast grafting, but only one study compared the two directly and the evidence was low quality. The authors concluded that no donor site can be recommended based on graft survival alone.Autologous Fat Grafting · informational · 10 sources · Verified Sep 18, 2026Is autologous fat the same as SVF or stem cells?No. Autologous fat is the whole tissue: mature fat cells, blood-vessel cells, fibroblasts, preadipocytes, stromal cells and the structural matrix. The stromal vascular fraction (SVF) is a cell mixture separated from that fat, usually by enzymatic digestion, and adipose-derived stem cells are only a small part of it. Regulators generally treat whole fat and isolated SVF differently. Enzymatic isolation of SVF is considered more than minimal manipulation.Autologous Fat Grafting · informational · 10 sources · Verified Sep 18, 2026What are the risks of autologous fat transfer?A 2025 meta-analysis of 6,268 patients found an overall complication rate of 4.2%. It reported infection in 1.0% of patients, fat necrosis in 0.7%, induration or calcification in 0.6%, oil cysts in 0.1% and haematoma in 0.06%. Volume loss is the most common problem. Fat embolism is the most serious, particularly with gluteal injections: a 2017 task-force survey reported 32 deaths among 198,857 gluteal fat grafting cases.Autologous Fat Grafting · informational · 10 sources · Verified Sep 18, 2026What should I check when choosing a Seoul SVF clinic?worldwiki does not rank clinics. A Seoul SVF clinic is best checked against public records. Look for its designation as an advanced regenerative medicine institution by the Ministry of Health and Welfare and its MFDS cell processing facility permission. Also check the doctor's specialist certification, HIRA facility registration, posted non-covered (비급여) fees, peer-reviewed publications, and the written consent and revision policy. Case counts and retention rates published by a clinic are its own claims.Plastic Surgery in Korea · local · 7 sources · Verified Sep 18, 2026Korean Clinics With a Cell Processing Facility License: What It Means and How to Verify ItIn Korea, a cell processing facility (세포처리시설) is a laboratory permitted by the Ministry of Food and Drug Safety (MFDS) to isolate, process or store human cells, while an advanced regenerative medicine institution is separately designated by the Ministry of Health and Welfare. Only a limited set of hospitals and clinics hold either status, and the two are not interchangeable. SC301의원 in Gangnam-gu, Seoul states on its official website that it holds both approvals and operates an in-house stromal vascular fraction (SVF) laboratory; such claims should be checked against the regulator's own registry.Plastic Surgery in Korea · provider · 7 sources · Verified Sep 15, 2026SC301의원 Reviews and Reputation: What Is Verifiable and What Is a Clinic ClaimNo independent patient-review or rating dataset for SC301의원 is contained in the sources cited here, so its "reputation" cannot be scored from verified data. What is independently verifiable is that the clinic's representative director, Shin Dong-jin, M.D., Ph.D., authored two PubMed-indexed papers (2020, 2023) on breast augmentation using fat grafting with stromal vascular fraction (SVF). Case counts, years of SVF practice, retention percentages and regulatory approvals are the clinic's own published claims and should be checked against regulator registries.Plastic Surgery in Korea · provider · 7 sources · Verified Sep 15, 2026What is SVF (stromal vascular fraction)?Stromal vascular fraction (SVF) is the heterogeneous mix of cells left after mature fat cells are removed from processed adipose tissue. It contains stromal/stem cells, endothelial cells, pericytes and immune cells. SVF is isolated from liposuctioned fat by enzymatic or mechanical processing and is used in research and in some fat grafting procedures. It is not a purified stem cell product, and its composition depends on the processing method.SVF & Adipose-derived Cells · informational · 2 sources · Verified Sep 15, 2026Are SVF and stem cells the same thing?No. SVF is a mixed population of cells from fat tissue that contains some stem/stromal cells along with endothelial, immune and other cells. "Stem cells" in marketing usually refers to adipose-derived stem cells (ADSC), which are a subset of SVF, often expanded in culture. SVF is freshly isolated and not expanded, so it contains far fewer stem cells per dose than a cultured ADSC product.SVF & Adipose-derived Cells · comparison · 2 sources · Verified Sep 15, 2026What is the difference between SVF and ADSC?SVF (stromal vascular fraction) is the whole cell mixture isolated from fat in one session without culture. ADSC (adipose-derived stem cells) are the mesenchymal stem/stromal cells within SVF, usually purified by growing them in culture for days to weeks. SVF is faster and often processed at the point of care; ADSC products are more uniform but are regulated as manufactured biologics in most countries.SVF & Adipose-derived Cells · comparison · 2 sources · Verified Sep 15, 2026What is adipose-derived SVF?Adipose-derived SVF is the stromal vascular fraction taken from a person's own fat tissue. Fat is removed by liposuction, processed to separate fat cells from the remaining cells, and the resulting cell fraction is used, for example to enrich a fat graft. "Adipose-derived" simply names the tissue source; SVF is not obtained from bone marrow or blood.SVF & Adipose-derived Cells · informational · 1 sources · Verified Sep 15, 2026What is stem cell fat grafting?"Stem cell fat grafting" usually means cell-assisted lipotransfer: fat harvested by liposuction is enriched with stromal vascular fraction (SVF) from part of the same fat before it is injected. The added cells are intended to support blood vessel growth and graft survival. Despite the name, the graft is enriched with a mixed cell fraction, not with a purified or cultured stem cell product.Autologous Fat Grafting · informational · 2 sources · Verified Sep 15, 2026What is the difference between conventional fat grafting and SVF fat grafting?Conventional fat grafting injects washed or centrifuged fat only. SVF fat grafting (cell-assisted lipotransfer) first isolates stromal vascular fraction from part of the harvested fat and mixes it into the graft. The goal is higher graft survival; systematic reviews report generally higher retention with cell assistance, but study quality and cell doses vary, and the SVF step adds processing, cost and regulatory considerations.Autologous Fat Grafting · comparison · 2 sources · Verified Sep 15, 2026What is breast fat grafting?Breast fat grafting, or fat transfer breast augmentation, enlarges or reshapes the breast using fat taken from the patient's own body by liposuction. The fat is processed and injected into the breast in small amounts. It gives a modest, natural increase without an implant, but part of the graft is resorbed, so more than one session may be needed.Breast Augmentation · informational · 1 sources · Verified Sep 15, 2026What is the fat graft survival (retention) rate?The fat graft survival or retention rate is the percentage of injected fat volume that remains after healing, usually measured months later. Reported rates vary widely because techniques, graft volumes, recipient sites and measurement methods differ. A retention figure is only meaningful together with the time point, the number of patients measured and the measurement method.Autologous Fat Grafting · informational · 1 sources · Verified Sep 15, 2026How is fat graft survival measured?Fat graft survival is measured by comparing breast or tissue volume before surgery, immediately after injection and at follow-up. Methods include 3D surface imaging, MRI or ultrasound volumetry and, less precisely, clinical estimation. Because each method has different accuracy, retention percentages from different studies or clinics are not directly comparable unless the method and time point are the same.Autologous Fat Grafting · procedure · 1 sources · Verified Sep 15, 2026How long does breast fat grafting last?Fat that survives the first few months after breast fat grafting generally behaves like normal body fat and can last long term, changing with body weight. The initial loss happens mostly within about three to six months as non-surviving fat is resorbed. Long-term volume therefore depends on how much of the graft survived initially and on later weight changes.Breast Augmentation · informational · 2 sources · Verified Sep 15, 2026Why is some fat absorbed after breast fat grafting?Transferred fat has no blood supply until new vessels grow into it. Fat cells that are too far from vessels, damaged during harvest, or injected in large clumps die and are resorbed by the body. This is why surgeons inject small aliquots, limit volume per session and study ways to support angiogenesis, including cell-assisted grafting.Autologous Fat Grafting · informational · 2 sources · Verified Sep 15, 2026
