vitreous cell

(redirected from hyalocyte)

vit·re·ous cell

a cell occurring in the peripheral part of the vitreous body that may be responsible for production of hyaluronic acid and possibly of collagen.

(10) In another study, histopathologic examination of ERM revealed the presence of vitreous hyalocytes, which supports the hypothesis that cells remaining on the retina surface following posterior vitreous detachment form a scaffold for ERM physiopathology.

Furthermore, several evidence indicate that VitC stimulates the proliferation of different mesenchyme-derived cell types including osteoblasts, adipocytes, chondrocytes, and odontoblasts [103, 108, 139-146], as well as the proliferation of immunologically relevant T cells [147] and hyalocytes (eye vitreous cells) [148].
Specifically, TGF-[beta]2, the main isoform in the posterior segment of the eye, activates Rho, leading to myosin light chain phosphorylation in hyalocytes [84], which is associated with actin-myosin interaction to form stress fibers and cell contraction [85, 86].
Alternatively, ERMs may result from the transdifferentiation (cell conversion) and proliferation of hyalocytes of vitreous origin that are left behind on the retinal surface following PVD.

It contains hyalocytes and densely packed collagen, similar to the vitreous base which covers the ora serrata [2].
Histological analysis of ERMs has demonstrated the presence of a range of different cell types, including retinal pigment epithelial cells, hyalocytes, fibrous astrocytes, glial cells and macrophages.

ROCK inhibitors are known to trigger an antifibrotic effect in several cell types in the eye, such as Tenon fibroblasts, the trabecular meshwork, retinal pigment epithelial cells, hyalocytes, and corneal stroma cells.
In the normal eye, TGF-[beta] has been revealed in photoreceptors, aqueous humor, hyalocytes of the vitreous body, and choroid [108], and its expression has proved to increase in PVR [82, 109].
