Liver Regeneration

Liver Regeneration

The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are large...

Tissue Renewal without Stem Cells

Tissue Renewal without Stem Cells

After cellular or tissue damage, the resident stem cells present in the human body can locally repair and regenerate the damaged tissue or organ. However, even though some tissues do not have stem cells, they can repair and regenerate with the help of pre-existing cells. For example, beta cells of the pancreas and hepatocytes of the liver can divide to renew and regenerate the tissue. Here, both cell division and cell death are well regulated by homeostasis.
However, failure of such a system...

Area of Science:

Biomedical Engineering
Regenerative Medicine
Oral Biology

Background:

Microvascular activation is crucial for oral wound healing, especially after laser injury.
CD31 is a key marker for angiogenesis and endothelial stability.
Plant-derived nanovesicles (PDNVs) show therapeutic potential but their effect on CD31 in laser wounds is unknown.

Purpose of the Study:

To evaluate how two PDNV formulations affect CD31 expression and microvascular density in laser-induced rabbit tongue wounds.
To compare the efficacy of Exoline and Glow exosomes in modulating vascular response.

Main Methods:

Standardized blue diode laser micro-incisions were created on rabbit tongues.
Wounds were treated with Exoline, Glow exosomes, or left untreated (control).
CD31 immunohistochemistry was used to quantify endothelial changes at baseline, Day 3, and Day 7.

Main Results:

Both PDNVs significantly increased CD31+ structures compared to controls.
Exoline promoted rapid CD31 expression, dense sprouting, and endothelial clustering by Day 3.
Glow showed moderate, consistent CD31 elevation and gradual vessel organization; Exoline wounds had mature networks by Day 7.

Conclusions:

PDNVs enhance CD31-mediated angiogenesis in laser-induced oral injuries.
Exoline demonstrated a more potent endothelial response and accelerated vascular remodeling.
PDNVs are promising for modulating microvascular repair in oral regenerative applications.
