    CD_99 G1 Neutrophils Modulate Osteogenic Differentiation of Mesenchymal Stem Cells in the Pathological Process of Ankylosing Spondylitis

    Single-cell RNA sequencing was used to identify cell populations and their gene signatures in the spinal enthesis of five patients with ankylosing spondylitis and three healthy individuals.

    CYP7B1-Mediated 25-Hydroxycholesterol Degradation Maintains Quiescence-Activation Balance and Improves Therapeutic Potential of Mesenchymal Stem Cells

    Scientists demonstrated that CYP7B1 was the common critical molecule that promoted activation and impeded quiescence of bone marrow-MSCs under inflammatory stimulation. Mechanistically, CYP7B1 degraded 25-hydroxycholesterol into 7α,25-dihydroxycholesterol.

    Isolation, Identification, and Osteogenic Capability Analysis of Mesenchymal Stem Cells Derived from Different Layers of Human Maxillary Sinus Membrane

    Human maxillary sinus membrane (hMSM) was isolated into a monolayer using the combined method of physical separation and enzymatic digestion. The localization of MSCs in hMSM was performed by immunohistological staining and other techniques.

    Abstract

    The RNA Binding Proteins LARP4A and LARP4B Promote Sarcoma and Carcinoma Growth and Metastasis

    The authors revealed that the RNA-binding proteins (RBPs) LARP4A and LARP4B were differentially overexpressed in osteosarcoma and osteosarcoma lung metastases, as well as in prostate cancer.

    Mesenchymal Stromal Cell Therapy for COVID-19 Acute Respiratory Distress Syndrome: A Double-Blind Randomised Controlled Trial

    Scientists conducted a randomized, placebo-controlled, double-blind clinical trial to assess the efficacy and safety of one bone marrow-derived MSC infusion in twenty patients with moderate to severe cute respiratory distress syndrome caused by COVID-19.

    Abstract

    3D Culture of Alginate-Hyaluronic Acid Hydrogel Supports the Stemness of Human Mesenchymal Stem Cells

    Researchers developed natural biomaterials, including hyaluronic acid, alginate, and gelatin, to mimic the creation of a 3D human MSC extracellular environment and selected hydrogels with high proliferation capacity for 3D MSC culture.

    Boosting Cartilage Repair with Silk Fibroin-DNA Hydrogel-Based Cartilage Organoid Precursor

    The authors developed a novel RGD-SF-DNA hydrogel microsphere via a microfluidic system by integrating photopolymerization with self-assembly techniques and then modified with Pep-RGDfKA.

    Apoptotic Extracellular Vesicles Derived from Hypoxia-Preconditioned Mesenchymal Stem Cells within a Modified Gelatine Hydrogel Promote Osteochondral Regeneration by Enhancing Stem Cell Activity and Regulating Immunity

    Researchers investigated whether apoptotic extracellular vesicles that were isolated from adipose-derived MSCs cultured under hypoxic conditions exerted greater effects on cartilage repair than those that are isolated from cells cultured under normoxic conditions.
