Can anyone with expert knowledge of this subject improve this to be read better as a definition for the laymen! This has been taken from an article on Monday 14 September 2009 (www.reuters.com). Thanks! >>>>> "Cytori Reports Preclinical Results that Suggest Adipose-Derived Regenerative Cells may Reverse Periodontal Disease: >>>>> Cytori Therapeutics (NASDAQ:CYTX) reported results from their preclinical study on the use of uncultured adipose-derived regenerative cells (ADRCs) in the treatment of critical periodontal defects in a rat model. The results suggest that the use of ADRCs may reverse the effects of periodontal disease, evidenced by significantly improved alveolar bone healing and decreased gingiva(gum) invasion of the defect. The data were reported today at the 95th Annual Meeting of the American Academy of Periodontology in Boston. >>>>> Severe periodontal disease (periodontitis) affects over 25% of the population in the U.S. alone. It is a painful condition that results in the decay of the bone and connective tissue that surround teeth that can ultimately lead to tooth loss. Currently, there is no generally accepted treatment with reliable results. These new study findings by Cytori may lead to new therapeutic treatments using ADRCs to treat and potentially reverse the effects of severe periodontitis. >>>>> As part of the study design, 20 immuno-deficient rats were treated for four critical defects in each. One of the defects was treated with uncultured human ADRCs and a second with cultured human adipose-derived stem cells (ADSC`s), both in Platelet Rich Plasma (PRP). A third was treated with PRP alone and a fourth with no treatment.>>>>> The study`s results showed that at six weeks post-treatment the defects treated with the uncultured ADRCs and with the cultured ADSCs showed a statistically significant (p>> About Cytori Cytori is committed to providing patients and physicians around the world with medical technologies, which harness the potential of adult stem and regenerative cells from adipose tissue. With the introduction of a family of medical devices, we have made a patient's own clinical grade stem and regenerative cells available to them at the point-of-care. The Celution® System family of medical devices and instruments is being sold into the European and Asian cosmetic and reconstructive surgery markets, while we seek regulatory clearance for it in the United States. Our StemSource® product line is sold globally for cell banking and research applications. www.cytoritx.com >>>>> Cautionary Statement Regarding Forward-Looking Statements >>>>> This press release includes forward-looking statements regarding events, trends and business prospects, which may affect our future operating results and financial position.

Skin stem cells are used in regenerative medicine to repair and regenerate damaged or diseased skin tissue. These cells have the ability to divide and differentiate into various types of skin cells, helping to promote healing and restore skin function. By harnessing the regenerative properties of skin stem cells, scientists and doctors can develop innovative treatments for conditions such as burns, wounds, and skin disorders.
The older the subject is, the less capable their stem cells are at being able to diversify into all types of cells.
Yes, most connective tissues have some degree of regenerative capacity due to the presence of stem cells. However, the extent of regeneration varies depending on the tissue type and the presence of blood supply. For example, bone and skin have relatively good regenerative capacity, while cartilage and tendons have limited regenerative ability.
Induced pluripotent stem cells are important in regenerative medicine because they can be reprogrammed to become any type of cell in the body, offering potential for personalized treatments and the ability to replace damaged or diseased tissues.
The stem cell uses the special regenerative cells which will help when the spinal cord is damaged.
Tissue lability depends on factors such as the turnover rate of cells, their regenerative capacity, and the presence of stem cells. Tissues with higher cell turnover rates, good regenerative potential, and abundant stem cells are considered more labile and capable of rapid repair and regeneration in response to damage or injury.
The regenerative layer of the epidermis is called the stratum basale. It is the deepest layer of the epidermis where new skin cells are formed through cell division. These new cells then migrate upwards to replenish the outer layers of the epidermis.
Skin stem cells are used in regenerative medicine to repair and rejuvenate tissues by replacing damaged or aging cells with new, healthy cells. These stem cells have the ability to differentiate into various cell types, allowing them to regenerate and repair damaged tissues in the skin. This process can help promote healing and improve the overall health and appearance of the skin.
Skin stem cells have the potential to be used in regenerative medicine for treating conditions like burns, wounds, and skin diseases. They can help regenerate damaged skin tissue and promote healing, offering new possibilities for personalized treatments and tissue engineering.
Cartilage has a limited regenerative capacity compared to many other tissues due to its avascular nature, meaning it lacks a direct blood supply. This limits the availability of nutrients and cells necessary for repair. In contrast, epithelial tissues have a higher regenerative capacity because they are richly supplied with blood vessels and have a high turnover rate, allowing them to quickly replace damaged cells. Ultimately, the differences in regenerative abilities stem from variations in blood supply, cellular turnover, and the structural characteristics of these tissues.
Mesenchymal stem cells are used for regenerative and tissue engineering. More information on the use of stem cells can found on Wikipedia, Regenexx, Euro Stem Cell and many more.
