Same-day cell fraction versus lab-expanded cells
Quick answer
SVF (stromal vascular fraction) is a mixed cell population separated from fat within a single day, containing only a modest share of stem cells. Cultured therapy instead selects and expands MSCs in a lab over 4-6 weeks, giving far higher cell numbers and fuller quality testing, at the cost of time and money.
SVF is convenient because everything happens in one day with no second flight. What you receive, though, is a mixture — endothelial cells, immune cells and some stem cells — so the true MSC dose varies with the patient and the isolation technique.
Culture gives more control: a known dose per infusion, a measured viability percentage and a full contamination screen before administration. In exchange it requires a GMP facility, and each country regulates expanded cells differently.
The choice depends on the goal. For local use alongside surgery or fat grafting, SVF may be enough. For chronic conditions needing higher, repeated doses, expanded cells from a GMP centre such as EHL Bio's offer better quality control.
Not entirely — SVF is a mixed population in which stem cells are only one component.
Each carries different risks — SVF from the same-day procedure, cultured cells from lab standards — so provider quality matters most.
