DUSP5 promotes osteogenic differentiation through SCP1/2 ‐dependent phosphorylation of SMAD1
DUSP5 promotes the osteogenic differentiation of mesenchymal stromal cells (MSCs) by repressing SMAD1 signaling pathway in a SCP1/2-dependent manner. The linker region of DUSP5 occupies the phosphatase domain of SCP1/2 and thereby releases the inhibitory effect of SCP1/2 on SMAD1 signaling. Additionally,Dusp5 overexpression could effectively ameliorate osteopenia of mice. AbstractDual-specificity phosphatases (DUSPs) are defined by their capability to dephosphorylate both phosphoserine/phosphothreonine (pSer/pThr) and phosphotyrosine (pTyr). DUSP5, a member of DUSPs superfamily, is located in the nucleus and plays cruciall...

Bone marrow ‐derived progenitor cells contribute to remodeling of the postpartum uterus
In conclusion, BM-derived progenitors were found to have a novel nonhematopoietic cellular contribution to postpartum uterus remodeling. This contribution may have an important functional role in p hysiological as well as pathological postpartum endometrial regeneration.© AlphaMed Press 2021Significance StatementThe uterus undergoes significant tissue regeneration in the postpartum period following parturition where endometrial stem cells are thought to play an important role. Here we show that bone marrow-derived progenitor cells actively participate in postpartum uterus remodeling in the mouse, undergoing dynamic change...

Hematopoietic Stem Cell Derived Functional Osteoblasts Exhibit Therapeutic Efficacy in a Murine Model of Osteogenesis Imperfecta
This study unequivocally establishes that transplanting HSCs can improve the clinical outcomes in OI due to the ability of HSCs to differentiate into osteoblasts, which lay down normal collagen. Therefore, HSC transplantation holds enormous translational potential and could become the therapy of choice for bone repair in OI and other bone diseases. (Source: Stem Cells)

Two DNA binding domains of MGA act in combination to suppress ectopic activation of meiosis ‐related genes in mouse embryonic stem cells
MGA bearing two distinct DNA-binding domains is a scaffolding component of PRC1.6 that prevents precocious and ectopic onset of meiosis in germ cells and ESCs, respectively. Here, we demonstrate that both Mga domains repress distinct sets of meiosis-related genes in ESCs. Our data also identifiedMeiosin as a linchpin molecule between positive and negative regulations of meiotic onset. AbstractAlthough the physiological meaning of the high potential of mouse ESCs for meiotic entry is not understood, a rigid safeguarding system is required to prevent ectopic onset of meiosis. PRC1.6, a non-canonical PRC1, is known for its su...

Cytokine and epigenetic regulation of programmed death ‐ligand 1 in stem cell differentiation and cancer cell plasticity
SOX2-mediated reprogramming of fibroblasts or cancer plasticity of lung cancer cells inhibits programmed death-ligand 1 (PD-L1) expression (upper). SOX2 expression is negatively associated with PD-L1 as well as HBEGF/EGFR and TGF- β signaling molecules (middle). SOX2 interacts with HDAC1, which silences PD-L1 expression (lower left). TGF-β induces PD-L1 expression via MEK pathway, while HBEGF/EGFR enhances PD-L1 expression through MEK and AKT pathways (lower right). AbstractProgrammed death-ligand 1 (PD-L1), an immune checkpoint ligand, is recognized as a potential target for cancer immunotherapy as well as for the induc...

Mitochondrial transfer from mesenchymal stem cells to macrophages restricts inflammation and alleviates kidney injury in diabetic nephropathy mice via PGC ‐1α activation
MSCs transfered mitochondria to M φ, which elicited Mφ into anti-inflammatory phenotype and ameliorated kidney injury through activation of PGC-1α. AbstractMesenchymal stem cells (MSCs) have fueled ample translation for treatment of immune-mediated diseases. Our previous study had demonstrated that MSCs could elicit macrophages (M φ) into anti-inflammatory phenotypes, and alleviate kidney injury in diabetic nephropathy (DN) mice via improving mitochondrial function of Mφ, yet the specific mechanism was unclear. Recent evidence indicated that MSCs communicated with their microenvironment through exchanges of mitochondr...

Human placenta mesenchymal stem cell protection in ischemic stroke is angiotensin converting enzyme ‐2 and masR receptor‐dependent
Angiotensin converting enzyme-2 (ACE-2) contributes to human placenta mesenchymal stem cell (hPMSC)-induced protection against ischemic injury through MasR pathway. AbstractThromboembolic stroke remains a major cause of neurological disability and death. Current stroke treatments (aspirin, tissue plasminogen activator) are significantly limited by timing and risks for hemorrhage which have driven researchers to explore other approaches. Stem cell-based therapy appears to be an effective option for ischemic stroke. Besides trans-differentiation into neural cells, stem cells also provide acute protection via paracrine signal...
