Adult zebrafish have a remarkable ability to completely regenerate cardiac muscle after injury. [7] There are similar genes in zebrafish and humans that control the development of the heart [8] and the phenomenal ability of zebrafish cardiomyocytes to proliferate in response to injury has made it a popular research model. When approximately 20% ...
The heart has the potential to repair itself when damaged using progenitor and stem cells. [10] Clinical trials have shown that heart muscle has not previously been able to regenerate itself. New noninvasive drugs, which may make this possible in humans, are required to induce the cardiac myocytes to proliferate.
Inhibition of p38 MAP kinase was found to induce mitosis in adult mammalian cardiomyocytes, [49] while treatment with FGF1 and p38 MAP kinase inhibitors was found to regenerate the heart, reduce scarring, and improve cardiac function in rats with cardiac injury. [50] One of the most promising sources of heart regeneration is the use of stem cells.
Dr. Kevin Watt, team leader of the Heart Regeneration and Disease Laboratory at the Murdoch Children’s Research Institute (MCRI) in Melbourne, Australia, understands this concept deeply.
[1] hECTs also have therapeutic potential for in vivo regeneration of heart muscle. [2] [3] hECTs provide a valuable resource to reproduce the normal development of human heart tissue, understand the development of human cardiovascular disease (CVD), and may lead to engineered tissue-based therapies for CVD patients. [3]
The existing epithelial cells can replicate, and, using the basement membrane as a guide, eventually bring the kidney back to normal. After regeneration is complete, the damage is undetectable, even microscopically. [citation needed] Healing must happen by repair in the case of injury to cells that are unable to regenerate (e.g. neurons).
A colony of human embryonic stem cells. Regenerative medicine deals with the "process of replacing, engineering or regenerating human or animal cells, tissues or organs to restore or establish normal function". [1]
