Trend in clinical trials using fresh SVF vs. culture expanded adipose-derived cells

This graph compares a number of clinical studies, involved  involved adipose tissue-derived Stromal Vascular Fraction (SVF) and stem cells expanded in culture.  Clinical studies, listed in international databases as trials.

Legend:

X axis: years, since 2011

Y axis: Relative % and number of "trials" newly listed in international registeries. It is not cumulative number - only listings, appeared between January 1 of particular year and January 1 of the next year.

Definitions:

Adipose tissue-derived cells include (1) freshly isolated SVF, used therapeutically at point-of-care and (2) cultured and ex-vivo expanded stem cells.
