The video shows how T cells, a type of white blood cell, go through a complex journey in the thymus to become mature immune cells ready to fight off infection. Given how essential the thymus is for a healthy immune system, ThymiStem scientists are trying to understand how to they can use stem cells to repair and regenerate this organ.
The thymus continues to grow after birth reaching the relative maximum size by puberty. [2] It is most active in fetal and neonatal life. [9] It increases to a mass of 20 to 50 grams by puberty. [3] It then begins to decrease in size and activity in a process called thymic involution. [4]
A thymectomy is an operation to remove the thymus. It usually results in remission of myasthenia gravis with the help of medication including steroids. However, this remission may not be permanent. Thymectomy is indicated when thymoma are present in the thymus. Anecdotal evidence suggests MG patients with no evidence of thymoma may still ...

Hassall's corpuscles (also known as thymic bodies) are structures found in the medulla of the human thymus, formed from eosinophilic type VI thymic epithelial cells arranged concentrically. These concentric corpuscles are composed of a central mass, consisting of one or more granular cells, and of a capsule formed of epithelioid cells.
Thymic involution is the shrinking of the thymus with age, resulting in changes in the architecture of the thymus and a decrease in tissue mass. [1] Thymus involution is one of the major characteristics of vertebrate immunology, and occurs in almost all vertebrates, from birds, teleosts, amphibians to reptiles, though the thymi of a few species of sharks are known not to involute.
Known as "Thymosin Fraction 5", this was able to restore some aspects of immune function in animals lacking thymus gland. Fraction 5 was found to contain over 40 small peptides (molecular weights ranging from 1000 to 15,000 Da.), [ 4 ] which were named "thymosins" and classified as α, β and γ thymosins on the basis of their behaviour in an ...
Kegel exercise, also known as pelvic floor exercise, involves repeatedly contracting and relaxing the muscles that form part of the pelvic floor, now sometimes colloquially referred to as the "Kegel muscles". The exercise can be performed many times a day, for several minutes at a time but takes one to three months to begin to have an effect.
