  1. Published articles were reviewed to overview how different research groups characterize their chondrocytes or chondroprogenitors originating from differentiated ES, iPSCs, MSCs, or chondrocytes. This table shows targeted genes and proteins in qPCR and immunoassays, histological stainings used, and which antigens were targeted with FACS.
