    Generation of iPSC-Derived Human Forebrain Organoids Assembling Bilateral Eye Primordia

    Investigators described a protocol to generate organoids with both forebrain entities called optic vesicles-containing brain organoids. They first induced neural differentiation and collect neurospheres, which they cultured in a neurosphere medium to initiate their patterning and further self-assembly.

    Abstract

    Directed Differentiation of Human iPSCs into Mesenchymal Lineages by Optogenetic Control of TGF-β Signaling

    Researchers reported the development of an optogenetic human iPSC system for TGF-β signaling and demonstrated its utility in directing differentiation into the smooth muscle, tenogenic, and chondrogenic lineages.

    Generation of Stable Integration-Free Pig Induced Pluripotent Stem Cells under Chemically Defined Culture Condition

    Scientists established an efficient induction system for exogenous gene-independent iPSCs under chemically defined culture condition previously used for generation of stable pig pre-gastrulation epiblast stem cells.

    Glycans in Spent Embryo Culture Medium Are Related to the Implantation Ability of Blastocysts

    A nested case-control study was conducted in Northwest women’s and children’s Hospital, Xi’an, China. The patients underwent fresh IVF/ICSI cycles with single blastocyst transfer were included. Total 78 cases were included and separated into groups according to success and failure implantation outcomes.

    Deletion of p66Shc Dysregulates ERK and STAT3 Activity in Embryonic Stem Cells, Enhancing Their Naïve-Like Self-Renewal in the Presence of LIF

    Researchers determined whether p66Shc could act as a negative regulator of extracellular signal regulated kinase (ERK) activity during embryonic development, antagonizing early lineage commitment.

    Abstract

    Parallel Genome-Wide CRISPR Screens to Identify State-Dependent Self-Renewal Regulators of Mouse Embryonic Stem Cells

    Parallel genome-wide CRISPR/Cas9 knockout screens were applied in ESCs cultured in the serum plus LIF and in the 2i plus LIF conditions. The candidate genes were classified into seven groups based on their positive or negative effects on self-renewal.
