We evaluated possible therapeutic effect of multipotent mesenchymal stromal cells from human adipose tissue differentiated to neuronal phenotype with retinoic acid on Wistar rats subjected to toxic effect of 3-nitropropionic acid. Transplantation of mesenchymal stromal cells from human adipose tissue considerably decreased neurological symptoms, normalized exploratory activity (open field test) and long-term memory (Morris test), which correlated with normalization of pathomorphological manifestations in the brain. Destructive changes in the caudate nucleus caused by treatment with 3-nitropropionic acid (reduced size of neurons, changes in their shape, and cell edema) tended to decrease under the effect of multipotent mesenchymal stromal cells: the area of neurons increased 2-fold, the cells acquired typical round shape, cell edema decreased.

One of the most obvious manifestations of the negative impact of space flight factors on the human physiology is osteopenia. With the active development of manned space flights and the increase in the duration of humans' persistence in weightlessness, there is a growing need to understand the mechanisms of changes occurring at the cellular level involved in the replenishment of bone tissue. Using the RNA sequencing method, changes in the transcriptome profile of MMSCs were studied after a 5-day simulation of the microgravity effects.

Osteoarthritis (OA) is a frequent chronic illness in orthopedics that poses a major hazard to patient health. cell therapy is emerging as a therapeutic option, but its efficacy is influenced by both the inflammatory milieu and the amount of stem cells, limiting its use. In this study, we designed a novel injectable porous microsphere (PM) based on microfluidic technology that can support mesenchymal stem cells (MSCs) therapy by combining polylactic-glycolic acid copolymer, kartogenin, polydopamine, stromal cell-derived factor-1, and copper-doped bioactive glass (CuBG).

Gastrointestinal stromal tumors (GIST), driven by KIT and PDGFRA mutations, are the most common mesenchymal tumors of the gastrointestinal tract. Although tyrosine kinase inhibitors (TKIs) have advanced treatment, resistance mutations and off-target toxicity limit their efficacy. This study develops covalent TKIs targeting drug-resistant GIST through structure-based design, synthesis, and biological evaluation.

While there is growing evidence highlighting the crucial role of the BM microenvironment (BMME) in MDS, the specific influence of inflammation on BMME changes, as well as the potential benefits of targeting cytokines therapeutically, remain to be elucidated. We previously found interleukin-1 (IL-1) to be a driver of aging phenotypes of BMME and hematopoietic stem and progenitor cells (HSPCs).

Cancer-associated fibroblasts (CAFs) are crucial stromal cells in the tumor microenvironment, affecting cancer growth, angiogenesis, and matrix remodeling. Developing an effective in vitro tumor model that accurately recapitulates the dynamic interplay between tumor and stromal cells remains a challenge. In this study, a 3D bioprinted fibroblast - mediated heterogeneous breast tumor model was created, with tumor cells and fibroblasts in a bionic matrix.
