Provided are methods and compositions from reprogramming human glial cells into human neurons. The reprogramming is achieved using combinations of compounds that can modify signaling via Transforming growth factor beta (TGF-β), Bone morphogenetic protein (BMP), glycogen synthase kinase 3 (GSK-3), and γ-secretase/Notch pathways. The reprogramming is demonstrated using groups of three or four compounds that are chosen from the group thiazovivin, LDN193189, SB431542, TTNPB, CHIR99021, DAPT, VPA, SAG purmorphamine. Reprogramming is demonstrated using the group of LDN193189/CHIR99021/DAPT, the group of B431542/CHIR99021/DAPT, the group of LDN193189/DAPT/SB431542, the group of LDN193189/CHIR99021/SB431542, a three drug combination of SB431542/CHIR99021/DAPT. Reprogramming using functional analogs of the compounds is also provided, as are pharmaceutical formulations that contain the drug combinations.
本文提供了将人类神经胶质细胞重编程为人类神经元的方法和组合物。这种重编程是利用能改变通过转化生长因子 beta(TGF-β)、骨形态发生蛋白(
BMP)、
糖原合酶激酶 3(GSK-3)和γ-分泌酶/Notch 通路的
信号转导的化合物组合来实现的。使用选自
噻唑ivin、LDN193189、SB431542、T
TNPB、CHIR99021、DAPT、VPA、
SAG purmorphamine 组的三或四种化合物组来证明重编程。使用 LDN193189/CHIR99021/DAPT 组、B431542/CHIR99021/DAPT 组、LDN193189/DAPT/SB431542 组、LDN193189/CHIR99021/SB431542 组、SB431542/CHIR99021/DAPT 三种药物组合进行了重编程演示。此外,还提供了使用这些化合物的功能类似物进行重编程的方法,以及含有这些药物组合的药物制剂。
