参与脊髓背侧模式的发育信号分子已在体内被鉴定;然而,研究尚未在体外产生特定功能的脊髓背侧神经元。我们在这里提出的R1胚胎干细胞(ES)分化为GABA能脊髓背侧神经元的顺序处理与发育信号分子。我们发现,视黄酸,BMP 4改变了神经祖细胞的规格,并指示神经命运时,在不同的发展阶段。高浓度的视黄酸启动尾部图案在早期分化; BMP 4诱导背侧发展。视黄酸与不同浓度的Bmp 4联合作用对脊髓不同区域的前体细胞有不同的调控作用。低浓度Bmp 4和高浓度视黄酸处理的拟胚体可诱导GABA能神经元分化。总之,我们证明了这种简单的治疗模式产生了简单的脊髓背侧神经元,可用于发育和临床前研究。
Developmental signaling molecules involved in dorsal patterning of the spinal cord have been identified in vivo; however, studies have not produced specific functional dorsal spinal cord neurons in vitro. We present here differentiation of R1 embryonic stem (ES) cells into GABAergic dorsal spinal cord neurons by sequential treatment with developmental signaling molecules. We found that retinoic acid, Bmp4 altered the specification of neural progenitors and instructed neural fate when applied at distinct stages of development. High concentration of retinoic acid initiated caudal patterning during early differentiation; Bmp4 induced dorsal development. The combination of retinoic acid and different concentration Bmp4 controlled the differing regional progenitors of spinal cord. Low-concentration Bmp4 and high concentration of retinoic acid-treated embryoid bodies resulted in the differentiation of GABAergic neurons. In summary, we demonstrate this simple treatment paradigm produced simple dorsal spinal cord neurons, which could be utilized for developmental and preclinical studies.
