The Tumorgenicity of Glioblastoma Cell Line U87MG Decreased During Serial In Vitro Passage.

abstract：:The transforming growth factor betas (TGFbetas) are context-dependent regulators of neurons in vitro, but their physiological functions in the brain are unclear. Haploinsufficiency of either Tgfbeta1 or Tgfbeta2 leads to age-related deterioration of neurons, but the development of the brain is normal in the full absen...
