Regenerative medicine is not new; it has not sprung anew out of stem cell science as has often been suggested. There is a rich history of study of regeneration, of development, and of the ways in which understanding regeneration advances study of development and also has practical and medical applications. This paper explores the history of regenerative medicine, starting especially with T.H. M...

Rocky Mountain forests are currently experiencing a bark beetle epidemic of unprecedented severity and extent. Forest regeneration following bark beetle outbreaks is driven by the survival and density of understory trees (advance regeneration). The composition and density of the advance regeneration may differ substantially from the pre-outbreak overstory and across environmental gradients. We ...

Vision, olfaction, hearing, and balance are mediated by receptors that reside in specialized sensory epithelial organs. Age-related degeneration of the photoreceptors in the retina and the hair cells in the cochlea, caused by macular degeneration and sensorineural hearing loss, respectively, affect a growing number of individuals. Although sensory receptor cells in the mammalian retina and inne...

stem cell-based therapy has great potential in treating health conditions including cardiovascular, autoimmune, type i diabetes, neurodegenerative and bone and cartilage diseases also in spinal cord injuries, malformations and cancer. in addition to their potential use to treat systemic diseases, stem cell-based therapy also provides a powerful tool to treat oral and dental diseases such as cra...

Stem cells, with their therapeutic potential in tissue repair and regeneration, have been widely used in translational medicine. Recent evidence suggests that the beneficial effects are mediated largely by their paracrine actions rather than the engraftment and differentiation at the injured sites. Extracellular vesicles (EVs), actively released from cells, play important roles in cell-to-cell ...

Regenerative medicine aims to restore normal tissue architecture and function. However, the basis of tissue regeneration in mammalian solid organs remains undefined. Remarkably, mice lacking p21 fully regenerate injured ears without discernable scarring. Here we show that, in wild-type mice following tissue injury, stromal-derived factor-1 (Sdf1) is up-regulated in the wound epidermis and recru...

Recent groundbreaking advances in organ bioengineering and regeneration have provided evidence that regenerative medicine holds promise to dramatically improve the approach to organ transplantation. The two fields, however, share a common heritage. Alexis Carrel can be considered the father of both regenerative medicine and organ transplantation, and it is now clear that his legacy is equally a...

A better understanding of the forces controlling cell growth will be essential for developing effective therapies in regenerative medicine and cancer. Historically, the literature has linked cancer and tissue regeneration-proposing regeneration as both the source of cancer and a method to inhibit tumorigenesis. This review discusses two powerful regeneration models, the vertebrate urodele amphi...

The article deals with the physiology of endometrial regeneration after its desquamation phase during menstrual cycle in women, as well an overview studies mesenchymal/stem cells main source tissue regeneration. processes that take place first their physiological essence are repair and regeneration, contrast to proliferation, which is based on regenerative neoplasm tissues, can be observed vari...
