Mayo Clinic Minute: Why bone marrow donor diversity is needed

Bone marrow transplants are procedures that infuse healthy blood stem cells into your body to replace damaged or diseased bone marrow. Just like people in need of solid organ transplants, such as hearts or kidneys, people in need of a bone marrow transplant have to find a matching donor. Dr. Ernesto Ayala, a Mayo Clinic [...]

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.

In this study, we investigated the link between AF and senescence markers through the assessment of protein expression in the tissue lysates of human appendages from patients in AF, including paroxysmal (PAF) or permanent AF (PmAF), and in sinus rhythm (SR). The major findings of the study indicated that the progression of AF is strongly related to the human atrial senescence burden as determined by p53 and p16 expression. The stepwise increase of senescence (p53, p16), prothrombotic (TF), and proremodeling (MMP-9) markers observed in the right atrial appendages of patients in SR, PAF, and PmAF points toward multiple inter...

Conclusions 1. For the first time rejuvenation therapy was started so late, at the point when half of the animals had already died, and the high (31 ± 5%) extension in maximal lifespan of the remaining animals was found. such significant effect on the maximal lifespan, unlike the median lifespan fluctuations, indicates that BM transplantation affects the intrinsic aging mechanism. The life-extending effect was significantly stronger than in earlier works with similar design (no irradiation or chemotherapy, no hereditary pathologies in recipients, advanced age at the start of the BM administration) because of (i) th...

This study aims to determine risk factors for the development of CA in patients undergoing HSCT.Methodology: A retrospective analysis of 138 consecutive patients undergoing HSCT at our institution between January 1st, 2015 and December 31st, 2017 was performed. One patient was excluded due to lack of baseline EKG. Data from patients ≥ 18 y/o who underwent autologous or allogeneic HSCT was analyzed. Variables analyzed included: age, gender, ethnicity, prior HSCT, diagnosis, type of transplant (autologous vs allogeneic), prior anthracycline exposure, diabetes mellitus, chronic kidney disease, hypertension, coronary artery...

This article is aimed to provide readers with an updated review on the applicability, efficacy, and challenges of employing donor apoptotic cell-based therapies to promote transplantation tolerance in various experimental and clinical settings. Recent findings Recently, donor apoptotic cell-based therapies have been employed in various models of cell (including pancreatic islets and bone marrow hematopoietic stem cells) and solid organ (heart and kidney) transplantation to promote donor-specific tolerance. Published data, thus far, have revealed a high potential of this approach in inducing robust transplantation tolera...

The modern era of transplantation began in the 1954 when Dr Murray performed the first successful kidney transplant operation. Just 2 years later, Dr Thomas and colleagues performed the first successful bone marrow transplant procedure. Both physicians received the Nobel Prize in physiology or medicine in 1990 for their groundbreaking work. In the 1960s, the first liver, heart, and lung transplant procedures were performed, with most patients experiencing suboptimal outcomes. Since then, outcomes have steadily improved.

This study didn't measure whether receiving the cardiosphere-derived cells extended lifespans, so we have a lot more work to do. We have much to study, including whether CDCs need to come from a young donor to have the same rejuvenating effects and whether the extracellular vesicles are able to reproduce all the rejuvenating effects we detect with CDCs." Cardiac and systemic rejuvenation after cardiosphere-derived cell therapy in senescent rats Cardiosphere-derived cell (CDC) therapy has exhibited several favourable effects on heart structure and function in humans and in preclinical models; however,...
