The column chromatography on silica gel, Sephadex LH-20 and semi-preparative HPLC were used to separate and purify the compounds from the EtOAc extract of medium and MeOH extract of cell cultures of Morus alba. Eight compounds were isolated. Based on physico-chemical properties and spectroscopic data, their structures were identified as isobavachalcone (1), genistein (2), norartocarpetin (3), albanin A (4), guangsangon E (5), mulberrofuran F (6), chalcomoracin (7), kuwanon J (8). Compounds 3-6 were isolated from the cell cultures of M. alba for the first time.

Due to its anatomical and physiological similarities to the human eye, the porcine eye serves as a robust model for biomedical research and ocular toxicity assessment. An air/liquid corneal culture system using porcine eyes was developed, and ex vivo epithelial wound healing was utilized as a critical parameter for these studies. Fresh pig corneas were processed for organ culture, with or without epithelial wounding.

Patterning soft materials with cell adhesion motifs can be used to emulate the structures found in natural tissues. While patterning in tissue is driven by cellular assembly, patterning soft materials in the laboratory most often involves light-mediated chemical reactions to spatially control the presentation of cell binding sites. Here we present hydrogels that are formed with two responsive crosslinkers-an anthracene-maleimide adduct and a disulfide linkage-thereby allowing simultaneous or sequential patterning using force and UV light.

Hepatic organoid cultures are a powerful model to study liver development and diseases in vitro. However, hepatocyte-like cells differentiated from these organoids remain immature compared to primary human hepatocytes (PHHs), which are the benchmark in the field. Here, we applied integrative single-cell transcriptome and chromatin accessibility analysis to reveal gene regulatory mechanisms underlying these differences.

Currently, incubators with a time-lapse system are widely used for in vitro embryo production in several species, however, their effect on alpaca embryo development compared to conventional incubators remains unknown. The aim of this study was to compare early in vitro embryo development in alpacas using a time-lapse incubator system versus a conventional incubator. Ovaries were obtained from a slaughterhouse and 1048 cumulus-oocyte complexes (COCs) were collected and in vitro matured for 26 h in either a time-lapse system (n = 542) or a conventional incubator (n = 542).
