火棉胶包埋能较好地保存组织,适于神经细胞及髓鞘染色,便于细胞构筑学研究。其特点在包埋过程中组织的收缩程度小,切片时变形也较少,是神经解剖学和连续脑切片常用方法。但其包埋过程复杂,时间较长,整个包埋过程长达十三周。作者经过多年切片染色实践过程中,摸索出一种新 Fire cotton embedding can better preserve tissue, suitable for nerve cells and myelin staining, facilitate cell structure research. Its characteristics in the embedding process of tissue contraction is small, the deformation is less, is a common method of neuroanatomy and continuous brain slices. However, its embedding process is complicated and takes a long time. The entire embedding process lasted for thirteen weeks. After many years of slicing the author practice, explore a new
