[Establishment of a human fetal thymocyte cell line and observation of its biological properties]

Thymocytes were isolated from a five month fetus after caesarean section and cultured in vitro. A cell line named human fetal thymocyte 8810 (HFT8810) was established and cultured continuously for 2 years in our lab, and grew well after recovery from the state of being frozen in liquid nitrogen. The HFT 8810 cells retained their ability to secrete thymosin after many generations in vitro culture.
