those stats are for regular fat transfer. supposedly the stem cell fat transfer has not been shown to have much benefit. a great place to look up research is Pubmed:

http://www.ncbi.nlm.nih.gov/pubmed

unless you are part of a university you won't have access to full articles but you can at least read abstracts. this site searches reputable journals for scientific research. it is the main source for anyone doing research or writing a paper, etc.

hope that helps!
