Osteocytes, the most common cell type within mature cortical bone, actively participate in the growth and maintenance of TCVs through the transfer of mitochondria to endothelial cells. Scanning electron microscopy images have revealed that osteocytes possess numerous dendritic processes with expanded, endfoot-like structures. These endfeet ...
This is a list of roots, suffixes, and prefixes used in medical terminology, their meanings, and their etymologies. Most of them are combining forms in Neo-Latin and hence international scientific vocabulary. There are a few general rules about how they combine.
Horizontal transfer of mitochondria is the movement of whole mitochondria and mitochondrial DNA between cells. Mitochondria from donor cells are transported and incorporated into the endogenous mitochondrial network of recipient cells contributing to changes in the bioenergetics profile and in other functional properties of recipient cells.

The mitochondrial permeability transition pore (mPTP or MPTP; also referred to as PTP, mTP or MTP) is a protein that is formed in the inner membrane of the mitochondria under certain pathological conditions such as traumatic brain injury and stroke.
This transport is regulated with chaperones and regulatory proteins which control the formation of the ER–mitochondria junction. Transfer of calcium from ER to mitochondria depends on high concentration of calcium in the intermembrane space, and mitochondrial calcium uniporter (MCU) accumulates calcium into the mitochondrial matrix for ...
Endothelium lines the inner wall of vessels, shown here. Microscopic view showing endothelium (at top) inside the heart. The endothelium forms an interface between circulating blood or lymph in the lumen and the rest of the vessel wall. This forms a barrier between vessels and tissues and control the flow of substances and fluid into and out of ...
Most mutations of mitochondrial membrane transporters are autosomal recessive. Mutations to transporters within the inner mitochondrial membrane mostly affect high-energy tissues due to the disruption of oxidative phosphorylation. [4] [44] For example, decreased mitochondrial function has been linked to heart failure and hypertrophy. This ...
Endothelial activation is a proinflammatory and procoagulant state of the endothelial cells lining the lumen of blood vessels. [1] It is most characterized by an increase in interactions with white blood cells (leukocytes), and it is associated with the early states of atherosclerosis and sepsis , among others. [ 2 ]
