Cytoplasmic fibrils
WebThe precise spacing and arrangement of the fibrils and lamellae are essential to stromal transparency. 42 The stroma is sparsely populated by quiescent, mesenchymal cells called keratocytes which are responsible for collagen production and turnover. 43,44 Stromal scarring can occur as a result of ocular trauma, surgery, or infection. Loss of ... WebThey have fewer fibrils within their cytoplasm, and cytoplasmic organelles are sparse, so that the somata are shaped by surrounding neurons and fibres. The processes of protoplasmic astrocytes also make contact with capillaries. Oligodendrocytes have few cytoplasmic fibrils but a well-developed Golgi apparatus.
