Production of nonhuman primate (NHP) embryos in vitro begins with recovery of gametes. Females undergo a controlled ovary stimulation to produce multiple preovulatory follicles from which oocytes may be recovered. Mature ova are subjected to in vitro fertilization (IVF) and presumptive zygotes are cultured to the intended stage of development. Essential to this practice is the culture medium unique to each step in the process. Here we describe medium preparation, oocyte recovery, in vitro fertilization, and in vitro culture (IVC) of embryos in the rhesus macaque model.

Background: Extracellular matrix (ECM) proteins play a crucial role in regulating the biological properties of adherent cells. For cryopreserved fibroblasts, a favourable ECM environment can help restore their natural morphology and function more rapidly, minimizing post-thaw stress responses.
Methods And Results: This study explored the functional responses of cryopreserved enriched caprine adult dermal fibroblast (cadFibroblast) cells to structural [collagen-IV and rat tail collagen (RTC)] and adhesion ECM proteins (laminin, fibronectin, and vitronectin) under in vitro culture conditions.

Background: The detection of drug-specific activation of T cells in the lymphocyte transformation test (LTT) is mainly based on cell proliferation or cytokine secretion. However, the LTT presents with a varying sensitivity and specificity. The aim of our study was to analyse the genome wide gene expression of PBMC to identify drug allergy-specific gene regulation patterns.

Background: The early stages of tumor bone metastasis are closely associated with changes in the vascular niche of the bone microenvironment, and abnormal angiogenesis accelerates tumor metastasis and progression. However, the effects of lung adenocarcinoma (LUAD) cells reprogrammed by the bone microenvironment on the vascular niche within the bone microenvironment and the underlying mechanisms remain unclear. This study investigates the effects and mechanisms of LUAD cells reprogrammed by the bone microenvironment on endothelial cells and angiogenesis, providing insights into the influence of tumor cells on the vascular niche within the bone microenvironment.

In-stent restenosis (ISR) following interventional therapy is a fatal clinical complication. Current evidence indicates that neointimal hyperplasia driven by uncontrolled proliferation of vascular smooth muscle cells (VSMC) is a major cause of restenosis. This implies that inhibiting VSMC proliferation may be an attractive approach for preventing in-stent restenosis.

At least 10% of proteins constituting the human proteome are subject to S-acylation by a long-chain fatty acid, thioesterified to a Cys thiol side chain. Fatty S-acylation (prototypically, S-palmitoylation) operates across eukaryotic phylogeny and cell type. S-palmitoylation is carried out in mammalian cells by a family of 23-24 dedicated zDHHC palmitoyl transferase enzymes, and mutation of zDHHCs is associated with a number of human pathophysiologies.
