Abstract The human fetal osteoblast cell line (hFOB 1. 19) has been proposed as an accessible experimental model for study of osteoblast biology relating to drug development and biomaterial engineering. For their multilineage differentiation potential. hFOB has been compared to human mesenchymal progenitor cells and used to investigate bone-metabolism in vitro. https://www.hcbcyouthleadersummit.com/product-category/lip-scrub/
