Skeletal stem cells (SSCs) are a population of progenitor cells which give rise to postnatal skeletal tissues including bone, cartilage and bone marrow stroma, however not to adipose, haematopoietic or muscle tissue. Growth plate chondrocytes exhibit the ability of continuous proliferation and differentiation, which contributes to the continuous physiological growth. The growth plate has been hypothesized to contain SSCs which exhibit a desirable differentiation capacity to generate bone and cartilage. Due to the heterogeneity of the growth plate chondrocytes, SSCs in the growth plate are not well studied. The present study used cluster of differentiation (CD)146 and CD105 as markers to isolate purified SSCs. CD105+ SSCs and CD146+ SSCs were isolated using a magnetic activated cell sorting method. To quantitatively investigate the proliferation and differentiation ability, the colony-forming efficiency (CFE) and multi‑lineage differentiation capacity of CD105+ SSCs and CD146+ SSCs were compared with unsorted cells and adipose-derived stem cells (ASCs). It was revealed that CD105+ and CD146+ subpopulations represented subsets of SSCs which generated chondrocytes and osteocytes, however not adipocytes. Compared with CD105+ subpopulations and ASCs, the CD146+ subpopulation exhibited a greater CFE and continuous high chondrogenic differentiation capacity in vitro. Therefore, the present study suggested that the CD146+ subpopulation represented a chondrolineage‑restricted subpopulation of SSCs and may therefore act as a valuable cell source for cartilage regeneration.

The neural tube, the embryonic precursor to the vertebrate central nervous system, comprises distinct progenitor and neuronal domains, each with specific proliferation programs. In this study, we identified TMEM196, a novel transmembrane protein that plays a crucial role in regulating cell proliferation in the floor plate in chick embryos. TMEM196 is expressed in the floor plate, and its overexpression leads to reduced cell proliferation without affecting the pattern formation of the neural tube.

The COVID-19 pandemic has emphasized the necessity for rapid and adaptable drug screening platforms against live pathogenic viruses that require high levels of biosafety containment. Conventional antiviral testing is time-consuming and labor-intensive. Here, we outline the design and validation of a semi-automated drug-screening platform for SARS-CoV-2 that utilizes multiple liquid handlers, a stable A549 cell line expressing ACE2 and TMPRSS2 receptors, and a recombinant SARS-CoV-2 strain harboring the nano-luciferase gene.

Pyroptosis, a form of programmed cell death, has recently emerged as a compelling molecular mechanism associated with the efficacy of chemotherapeutic drugs in tumor treatment. OSW-1, derived from the bulbs of Ornithogalum saundersiae Baker, exhibits a diverse range of pharmacological effects. However, its specific antitumor effects on colorectal cancer (CRC) and the mechanisms underlying these effects remain elusive.

Human brain organoids (HBOs) derived from pluripotent stem cells hold great potential for disease modeling and high-throughput compound screening, given their structural and functional resemblance to fetal brain tissues. These organoids can mimic early stages of brain development, offering a valuable in vitro model to study both normal and disordered neurodevelopment. However, current methods of generating HBOs are often low throughput and variable in organoid differentiation and involve lengthy, labor-intensive processes, limiting their broader application in both academic and industrial research.

Human liver organoids (HLOs) derived from pluripotent stem cells hold potential for disease modeling and high-throughput compound screening due to their architectural and functional resemblance to human liver tissues. However, reproducible, scale-up production of HLOs for high-throughput screening (HTS) presents challenges. These include the high costs of additives and growth factors required for cell differentiation, variability in organoid size and function from batch to batch, suboptimal maturity of HLOs compared to primary hepatocytes, and low assay throughput due to excessive manual processes and the absence of assay-ready plates with HLOs.
