Angiotensin II, oxidative stress, and stem cell therapy: a matter of delicacy

Optimisation of stem cell therapy after cardiovascular and renal injury depends on many factors, amongst which stem cell donor health. The renin-angiotensin system (RAS), plays an important role in cardiovascular and renal homeostasis and pathophysiology. It is becoming increasingly clear that the RAS affects the therapeutic performance of stem cells. In the present issue of Clinical Science Kankuri et al. dig deeper into the consequences of excessive angiotensin II signaling and reactive oxygen species (ROS) formation in the stem cell donor, applying a model of regenerative medicine after renal injury.

ElmazarAbstractTreatment of breast cancer by paclitaxel (PAX) often encounters therapeutic failure most likely caused by innate/acquired resistance. Cancer stem cells (CSCs) and multidrug resistance complex (MDR-1 or P-glycoprotein) overexpression are main mechanisms implicated in chemoresistance. Increased aldehyde dehro...

Larger business analysis concerns are starting to notice that the longevity industry exists. I point out this press release not because the contents are all that interesting or useful - it is very much business as usual in the white paper production community, and the people creating these materials typically have a poor understanding of the biology and the biotechnology - but rather as an indication of progress towards a broader appreciation of the potential to treat aging as a medical condition. Slowly, the eyes of the world are opened. The global longevity and anti-senescence market will witness rapid growth ov...

Whether blastomere-like extended pluripotent stem cells (EPS cells) retain a similar generative capacity remains unknown. Here, we established a 3D differentiation system that enabled the generation of blastocyst-like structures from EPS cells (EPS-blastoids) through lineage segregation and self-organization. EPS-blastoids resembled blastocysts in morphology and c...

The host-pathogen interface is a crucial battleground during bacterial infection in which host defenses are met with an array of bacterial counter-mechanisms whereby the invader aims to make the host environment more favorable to survival and dissemination. Interestingly, the eukaryotic Wnt signaling pathway has emerged as a key player in the host and pathogen tug-of-war. Although studied for decades as a regulator of embryogenesis, stem cell maintenance, bone formation, and organogenesis, Wnt signaling has recently been shown to control processes related to bacterial infection in the human host. Wnt signaling pathways con...

AbstractPurpose of ReviewWith the rapid and ongoing evolution of regenerative and sports medicine, the use of stem/stromal cells in ligament repair and reconstruction continues to be investigated and grow. The purpose of this review was to assess available methods and formulations for stem/stromal cell augmentation as well as review early pre-clinical and clinical outcomes for these recently emerging techniques.Recent FindingsRecent literature demonstrates promising outcomes of stem/stromal cell augmentation for ligament repair and reconstruction. Multiple groups have published animal models suggesting improved healing for...

The resulting deficiency of alpha L-iduronidase enzyme leads to a progressive accumulation of glycosaminoglycans in lysosomes which damages multiple organs and highly reduces life expecta...
