Smooth muscle contraction of the epididymis plays an important role in sperm transport. Although PDGFRα-positive interstitial cells (PDGFRα (+) ICs) are thought to be involved in controlling smooth muscle movement via intercellular signaling, they have not yet been reported to date in the epididymis. Therefore, we aimed to investigate the morphological characteristics of PDGFRα (+) ICs in the interstitial space of the murine epididymis. Immunohistochemistry showed that PDGFRα (+) ICs co-labeled with CD34 (PDGFRα (+) CD34 (+) ICs were distributed in the interstitial space of the murine epididymis from the initial segment (IS) to the cauda of the epididymis. PDGFRα (+) ICs that were not co-labeled with CD34 (PDGFRα (+) CD34 (−) ICs) were observed just beneath the epithelium from the corpus to the cauda but not in the IS. Both types of PDGFRα (+) ICs were in close proximity to each other as well as the surrounding nerves and macrophages. In addition, PDGFRα (+) CD34 (−) ICs beneath the epithelium were also in close proximity to the basal cells. Using transmission electron microscopy, we identified ICs that possessed elongated and woven cellular processes and were in close proximity to each other, surrounding the cells in the interstitial space. In the murine epididymis, it is suggested that there are two subtypes of ICs that show different distribution patterns depending on the segment, which may reflect segmental differences in mechanisms of sperm transport, forming a cellular network by physical interactions in the murine epididymis.

光学显微镜和透射电子显微镜对小鼠附睾间质细胞的形态学分析

附睾的平滑肌收缩在精子运输中起重要作用。尽管 PDGFRα 阳性间质细胞 (PDGFRα (+) ICs) 被认为参与通过细胞间信号传导控制平滑肌运动,但迄今为止尚未在附睾中报道它们。因此,我们旨在研究小鼠附睾间质空间中 PDGFRα (+) IC 的形态特征。免疫组织化学显示,与 CD34 共标记的 PDGFRα (+) ICs (PDGFRα (+) CD34 (+) ICs 分布在小鼠附睾的间质空间,从附睾的初始节段 (IS) 到附睾尾端。PDGFRα (+) ) 未与 CD34 共标记的 IC (PDGFRα (+) CD34 (-) IC) 在从体部到马尾的上皮下方观察到,但在 IS 中没有。两种类型的 PDGFRα (+) IC 彼此以及周围的神经和巨噬细胞都非常接近。此外,上皮下的 PDGFRα (+) CD34 (-) ICs 也非常靠近基底细胞。使用透射电子显微镜,我们确定了具有细长和编织细胞过程的 IC,并且彼此非常接近,围绕着间隙空间中的细胞。在小鼠附睾中,有两种亚型的ICs根据节段表现出不同的分布模式,这可能反映了精子运输机制的节段差异,通过小鼠附睾中的物理相互作用形成细胞网络。上皮下的 PDGFRα (+) CD34 (-) ICs 也非常靠近基底细胞。使用透射电子显微镜,我们确定了具有细长和编织细胞过程的 IC,并且彼此非常接近,围绕着间隙空间中的细胞。在小鼠附睾中,有两种亚型的ICs根据节段表现出不同的分布模式,这可能反映了精子运输机制的节段差异,通过小鼠附睾中的物理相互作用形成细胞网络。上皮下的 PDGFRα (+) CD34 (-) ICs 也非常靠近基底细胞。使用透射电子显微镜,我们确定了具有细长和编织细胞过程的 IC,并且彼此非常接近,围绕着间隙空间中的细胞。在小鼠附睾中,有两种亚型的ICs根据节段表现出不同的分布模式,这可能反映了精子运输机制的节段差异,通过小鼠附睾中的物理相互作用形成细胞网络。包围间隙中的细胞。在小鼠附睾中,有两种亚型的ICs根据节段表现出不同的分布模式,这可能反映了精子运输机制的节段差异,通过小鼠附睾中的物理相互作用形成细胞网络。包围间隙中的细胞。在小鼠附睾中,有两种亚型的ICs根据节段表现出不同的分布模式,这可能反映了精子运输机制的节段差异,通过小鼠附睾中的物理相互作用形成细胞网络。
