Epithelial cells and endothelial cells are two types of cells that line body surfaces. In this disease, epithelial cells invade the intraocular structures through an incompetent wound and proliferate wildly causing pain and vision loss through a variety of mechanisms. These cell types often exist at an interface between two vastly different (micro)environments. Endothelial cells allow fluid to move between the cornea and the anterior chamber, ... (epithelial or stromal edema), abnormal vessel growth (pannus and neovascularization), corneal infiltrates (accumulation of inflammatory WBCs), corneal ulceration and immune-mediated inflammation. Main Difference – Epithelial vs. Mesenchymal Cells. So, if the patient has epithelial ingrowth that’s causing astigmatism and you can use trial glasses to get her to 20/20 and she says she likes that vision, then it’s OK to do a PRK to counteract the astigmatism from the ingrowth. Though surgeons say the ingrowth of epithelial cells beneath the LASIK flap isn’t as common as it once was, it can still occur, so it pays to be prepared for it if and when it appears. In addition, they are in glands. Views: 550. 1. In particular, they form the barrier between the blood and the internal environment. The main difference between epithelial and endothelial cells is that epithelial cells line both internal surfaces and external surfaces of the body whereas endothelial cells line the internal surfaces of the components of the circulatory system.

Columnar Epithelium – The columnar epithelium has cells that are pillar-like and column-like. The disease occurs when these cells slowly start to die off. For instance, the outermost layer of the skin, the epidermis, is nothing but the epithelium. save. The similarities include common organelles like cell membrane, cell nucleus, mitochondria, endoplasmic reticulum, ribosomes and golgi apparatus. Endothelial cells form the barrier between vessels and tissue and control the flow of substances and fluid into and out of a tissue. However, three renal epithelial cell lines (two tubular and one glomerular) showed little or no PR3 expression by PCR or ELISA. Importantly, endothelial cell dysfunction can contribute to vascular diseases, such as atherosclerosis. Specialized epithelial cells located in the skin, nose, tongue, and eyes interact with the nerve endings, which help detect sensory stimuli.
