Due to the single-cell origin of non-zygotic embryos, they are preferred in several regeneration systems for micropropagation, ploidy manipulation, gene transfer, and synthetic seed production. Nonetheless, tissue regeneration via organogenesis has also proved to be advantageous for studying regulatory mechanisms of plant development.
Micro-mass cultures of C3H-10T1/2 cells at varied oxygen tensions stained with Alcian blue. A commonly applied definition of tissue engineering, as stated by Langer [3] and Vacanti, [4] is "an interdisciplinary field that applies the principles of engineering and life sciences toward the development of biological substitutes that restore, maintain, or improve [Biological tissue] function or a ...
For studies of regeneration urodele amphibians such as the axolotl Ambystoma mexicanum are used, [53] and also planarian worms such as Schmidtea mediterranea. [10] Organoids have also been demonstrated as an efficient model for development. [54] Plant development has focused on the thale cress Arabidopsis thaliana as a model organism. [55]
Cellular atrophy is a decrease in cell size. If enough cells in an organ undergo atrophy the entire organ will decrease in size. Thymus atrophy during early human development (childhood) is an example of physiologic atrophy. Skeletal muscle atrophy is a common pathologic adaptation to skeletal muscle disuse (commonly called "disuse atrophy").
Development and regeneration involves the coordination and organization of populations cells into a blastema, which is "a mound of stem cells from which regeneration begins". [25] Dedifferentiation of cells means that they lose their tissue-specific characteristics as tissues remodel during the regeneration process.
Epimorphosis is defined as the regeneration of a specific part of an organism in a way that involves extensive cell proliferation of somatic stem cells, [1] dedifferentiation, and reformation, [2] as well as blastema formation. [3]
For instance, if you’re following a plant-based diet, you may struggle to meet your daily protein needs through whole foods alone. In this case, incorporating a scoop of protein powder into ...
Osteoarthritis is the main cause of joint pain both in animals and humans. Horses and dogs are most frequently affected by arthritis. Natural cartilage regeneration is very limited. Different types of mesenchymal stem cells and other additives are still being researched to find the best type of cell and method for long-term treatment. [23]
