Abstract

Lima1 is an extensively studied prognostic marker of malignancy and is also considered to be a tumour suppressor, but its role in a developmental context of non-transformed cells is poorly understood. Here, we characterise the expression pattern and examined the function of Lima1 in mouse embryos and pluripotent stem cell lines. We identify that Lima1 expression is controlled by the naïve pluripotency circuit and is required for the suppression of membrane blebbing, as well as for proper mitochondrial energetics in embryonic stem cells. Moreover, forcing Lima1 expression enables primed mouse and human pluripotent stem cells to be incorporated into murine pre-implantation embryos. Thus, Lima1 is a key effector molecule that mediates the pluripotency control of membrane dynamics and cellular metabolism., How pluripotency transcription factors regulate the cellular architecture and energetics has remained largely unknown. Here the authors identify Lima1 as a key effector that mediates the pluripotency control of membrane dynamics and cellular metabolism.

Abstract

The article presents a study which aimed to decipher the mechanisms of lumenogenesis and the role of the proamniotic cavity using the 3D ES model of epiblast development in combination with direct analyses in early mouse embyros. Topics discussed include the changes in the mouse embryo during the peri-implantation stages, findings on the cavity formation, and the function of the proamniotic cavity.

Abstract

Electron microscopy samples processed for cryo-immunogold-labeling need to be gently fixed to keep their antigenicity. Biological material like cultured cells or tissue can be prepared according to the standard Tokuyasu fixation or in a further developed rehydration method based on high-pressure freezing. We will describe here the variant and common steps of both methods in detail and illustrate their potency in the ultrastructural imaging of peroxisomes.
