| Full Information |
NCH421K is a human glioblastoma stem-like cell line derived from a primary glioblastoma tumor obtained from an adult patient. This cell line belongs to a class of tumor-initiating cells that retain key features of neural stem cells, including self-renewal capacity, multipotency, and the ability to recapitulate tumor heterogeneity. NCH421K cells are typically cultured under serum-free conditions and grow as non-adherent neurospheres, a hallmark of stem-like glioma cultures. They express canonical stem cell markers such as CD133 and nestin, supporting their classification as a glioblastoma stem-like model.
NCH421K exhibits growth and survival that are strongly dependent on basic fibroblast growth factor (bFGF), which promotes proliferation and maintenance of stem-like characteristics, whereas epidermal growth factor (EGF) has minimal effect on its expansion. The cells maintain high expression of stem cell markers under bFGF stimulation and demonstrate the ability to form tumors in vivo, highlighting their tumorigenic potential. Due to these properties, NCH421K is widely used in studies of glioblastoma stem cell biology, therapeutic resistance, differentiation strategies, and the evaluation of targeted treatments aimed at eradicating tumor-initiating cell populations.
This cell line was established by Christel Herold-Mende from glioblastoma tissue.
Společnost Cytion vznikla v roce 2004 v německém Heidelbergu s jasným vědeckým posláním: dodávat ověřené lidské a zvířecí buněčné linie bez kontaminace, připravené za přísně kontrolovaných laboratorních podmínek.
Postupně se vypracovala ve spolehlivou buněčnou banku, která slouží akademickým laboratořím, biotechnologickým firmám i farmaceutickým výzkumným týmům po celém světě. Klade přitom důraz na reprodukovatelnost výsledků, přísnou kontrolu kvality a dlouhodobá partnerství.
