Cell therapy of critical limb ischemia-problems and prospects.

Cell therapy of critical limb ischemia-problems and prospects. Vasa. 2019 Apr 10;:1-11 Authors: Osipova O, Saaya S, Karpenko A, Zakian S, Aboian E Abstract Cell therapy is proposed for indirect revascularization for the patient's incurable by endovascular or surgical revascularization. The therapy with stem cells (SCs) or progenitor cells is assumed to be more efficient as compared with protein or gene therapy not only because of their direct vasculogenic properties, but also thanks to their paracrine effect via secretion of manifold biologically active substances. This review gives an overview of the potential of SC-based therapy for critical limb ischemia (CLI), putative mechanism underlying cell therapy, and comparison of cell therapy to angiogenesis gene therapy in CLI treatment. Human trial data and meta-analysis, as well as some problems of clinical trials and considerations for future SC-based therapy in CLI are also discussed.

In conclusion, taller body height at the entry to adulthood, supposed to be a marker of early-life environment, is associated with lower risk of dementia diagnosis later in life. The association persisted when adjusted for educational level and intelligence test scores in young adulthood, suggesting that height is not just acting as an indicator of cognitive reserve.

p19Arf sensitizes B16 melanoma cells to interferon-β delivered via mesenchymal stem cells in vitro. Braz J Med Biol Res. 2020;53(3):e8876 Authors: Da-Costa RC, Vieira IL, Hunger A, Tamura RE, Strauss BE Abstract The immune stimulatory and anti-neoplastic functions of type I interferon have long been applied for the treatment of melanoma. However, the systemic application of high levels of this recombinant protein is often met with toxicity. An approach that provides localized, yet transient, production of type I interferon may overcome this limitation. We propose that the use of mesenchymal stem ...

Stem cell populations become damaged and dysfunctional with age. Some of this is issues with the stem cells themselves, and some of this results from problem with the signaling environment and function of the stem cell niche. Which of these factors is more important likely varies by stem cell population. Among the best studied of stem cell types, the evidence suggests that muscle stem cells remain capable in old age, but become ever more quiescent, while hematopoietic stem cells become damaged and dysfunctional, unable to perform. Hematopoietic stem cells reside in the bone marrow and are responsible for generating blood a...

This is the latest in a series of yearly posts in which I suggest areas of development for biotech startups I'd like to see actively developed as a part of the longevity industry in the near future. Today, this year, is a good time to be starting a company focused on the production of a novel therapeutic approach to intervening in the aging process. There is a great deal of funding for seed stage investment, and many compelling projects lacking champions, yet to be carried forward from academia into preclinical development. Numerous scientific and industry crossover conferences are now held every year, at which it is possi...

Researchers here report that transplanting bone marrow from young donor mice into old recipient mice produces a range of benefits, such as improvement in the behavior of macrophage cells. Bone marrow stem cells are responsible for producing blood and immune cells, among other important populations, and this capability is degraded in a number of ways with age. Introducing younger stem cells and their supporting structures is a plausible means to at least partially reverse this process. That said, this sort of approach is unlikely to arrive in human medicine in exactly the same form, given the challenges involved in bone mar...

However, NSCs become increasingly quiescent with age, which hampers their regenerative capacity. New means are therefore required to genetically modify adult NSCs for re-enabling endogenous brain repair. Recombinant adeno-associated viruses (AAVs) are ideal gene therapy vectors due to an excellent safet...

Telomerase gene therapy is considered in some quarters to be a viable treatment for aging. Telomeres are the caps of repeated DNA sequences at the ends of chromosomes. They are an important part of the mechanism limiting the number of times that somatic cells in the body can divide, the Hayflick limit. A little telomere length is lost with each cell division, and short telomeres trigger cellular senescence or programmed cell death, halting replication. Stem cell populations use telomerase to lengthen their telomeres and thus self-renew to provide a continual supply of new somatic daughter cells with long telomeres to repla...

However, it is unclear whether and how the circadian clock proteins regulate stem cell aging. Here, we identified a noncanonical transcriptional activator-independent role of CLOCK, a core component of the molecular circadian clock machinery, in counteracting human mesenchymal stem cell (hMSC) senescence. CLOCK expressio...
