Comparison of Human Platelet Lysate versus Fetal Bovine Serum for Expansion of Human Articular Cartilage-Derived Chondroprogenitors.

This is the first in vitro xeno-free study to affirm that hPL can serve as an optimal growth supplement for expansion of articular chondroprogenitors, although an in-depth assessment of resident growth factors and evaluation of different dilutions of hPL is required to assess suitability for use in translational research.
