Dynamics of development of the cerebral cortex tissue anlage in 17-day-old embryos of Wistar rats, implanted into the sciatic nerve of mature rats with the aim to establish new relay and trophic centers in the regenerating nerve have been studied. By means of certain morphological methods (silver nitrate impregnation after Bielschowsky-Gros, Sudan black, hematoxylin-eosin, toluidine blue after Nissl stainings) it has been stated that the implanted nerve cells not only preserve their viability, but also differentiate from neuroblasts up to young and mature neurons during 2 months. Already in 14 days after the operation there are blood vessels in the implants; by the 2d month massive myelinization of axons begins in the implant. A part of the regenerating myelin fibers of the nerve gets into the implant and branches. In similar cases connections between the implanted neurons and the host peripheral nervous fibers are supposed to be established.
对植入成年大鼠坐骨神经的17日龄Wistar大鼠胚胎大脑皮质组织原基的发育动态进行了研究，目的是在再生神经中建立新的中继和营养中心。通过某些形态学方法（Bielschowsky-Gros法硝酸银浸染、苏丹黑、苏木精-伊红、Nissl染色后的甲苯胺蓝）表明，植入的神经细胞不仅保持其活力，而且在2个月内从神经母细胞分化为年轻和成熟的神经元。术后14天植入物中就已有血管；到第2个月，植入物中轴突开始大量髓鞘化。神经再生的髓鞘纤维一部分进入植入物并分支。在类似情况下，推测植入的神经元与宿主外周神经纤维之间建立了连接。
