神经胶质瘤是脊椎动物视网膜上最丰富的神经胶质瘤,它具有复杂的形态,其特征是在视网膜上有一个垂直的茎,在每一层视网膜上都有分支。神经胶质细胞在视网膜内稳态中发挥着多种关键作用,这可能是由于它们复杂的解剖结构所致。然而,仍有许多未知,特别是在小鼠中,关于<s:1>勒细胞及其乔木的解剖排列,以及这些特征在发育过程中是如何出现的。本研究利用膜靶向荧光蛋白揭示小鼠腋窝的精细结构。我们发现内部丛状层(IPL)内的亚层特异性乔木专门化始终发生在定义的层流位置。然后,我们描述了<s:1> ller神经胶质空间模式,揭示了单个细胞如何协作形成泛视网膜网络。与神经元不同,突触细胞分布在视网膜上,密度均匀,其乔木大小随偏心量变化不大。使用“Brainbow”方法以不同的颜色标记相邻细胞,我们发现m<s:1> ller胶质细胞以最小的重叠覆盖视网膜空间。它们的乔木形状不规则但非随机,表明邻近细胞之间的局部相互作用决定了它们的领土。最后,我们确定了一个发育窗口,即出生后6-9天,当m<s:1> ller木叶第一次定植于突触层时,从定型IPL下开始。总之,我们的研究定义了小鼠<s:1>勒神经胶质细胞及其在视网膜径向和切向平面上的解剖排列,在发育和成年期。神经胶质瘤组织的局部精度表明,它们的形态是由特定的细胞与神经元以及彼此之间的相互作用塑造的。
Müller glia, the most abundant glia of vertebrate retina, have an elaborate morphology characterized by a vertical stalk that spans the retina and branches in each retinal layer. Müller glia play diverse, critical roles in retinal homeostasis, which are presumably enabled by their complex anatomy. However, much remains unknown, particularly in mouse, about the anatomical arrangement of Müller cells and their arbors, and how these features arise in development. Here we use membrane-targeted fluorescent proteins to reveal the fine structure of mouse Müller arbors. We find sublayer-specific arbor specializations within the inner plexiform layer (IPL) that occur consistently at defined laminar locations. We then characterize Müller glia spatial patterning, revealing how individual cells collaborate to form a pan-retinal network. Müller cells, unlike neurons, are spread across the retina with homogenous density, and their arbor sizes change little with eccentricity. Using “Brainbow” methods to label neighboring cells in different colors, we find that Müller glia tile retinal space with minimal overlap. The shape of their arbors is irregular but non-random, suggesting local interactions between neighboring cells determine their territories. Finally, we identify a developmental window at postnatal days 6–9 when Müller arbors first colonize the synaptic layers beginning in stereotyped IPL sublaminae. Together, our study defines the anatomical arrangement of mouse Müller glia and their network in the radial and tangential planes of the retina, in development and adulthood. The local precision of Müller glia organization suggests that their morphology is sculpted by specific cell-cell interactions with neurons and each other.
