人骨肉瘤细胞 disease models

MG-63 (osteosarcoma / osteoblast-like) classic parental modeling page with foolproof steps, flowcharts, and PubMed refs. May add ALP/mineralization readouts (osteoblast-like outlines). Optimize per datasheet/pilots; RUO.

Adapted from PubMed literature for research use only (RUO); adjust per lab SOP and pilots.

Use case

Use MG-63 to test compound/genetic effects on proliferation/survival.
