Project description:Partial exon deletion in Trpm7 gene was confirmed by lack of transcripts according to the RNA sequencing in two stem cell clones. For this mice were genetically modified by partial deletion of exon 2 and embryonic stem (ES) cell lines were generated. Isolated RNA of two ES clones was sequenced with Illumina NextSeq 500 Sequencer, which generated 75 bases long ‘single-end’ reads.
Project description:TRPM7 is a ubiquitous ion channel and kinase, a unique ‘chanzyme’, required for proper early embryonic development. In order to assess the effects of TRPM7 activity on cellular gene expression, mouse embryonic stem cells with TRPM7 gene deletion (TRPM7-/- mESC) were established. By using microarray analysis, we identified genes with transcription significantly different in TRPM7-deficient mESC.

In order to assess the effects of TRPM7 activity on cellular gene expression, mouse embryonic stem cells with TRPM7 gene deletion (TRPM7-/- mESC) were established. By using microarray analysis, we identified genes with transcription significantly different in TRPM7-deficient mESC. Total RNA was extracted from cells using Qiagen RNAeasy Plus mini Kit. Triplicate samples were made for each wild type clone 3 (WT3) and and TRPM7-/- clone 9 (KO9) mESC
Project description:There are no described quality assurance mechanisms for newly formed stem cells. We observed intimate interactions between macrophages and blood stem cells in zebrafish embryos. Stressed stem cells were marked by surface Calreticulin, which stimulates macrophage interaction as an eat me signal. Macrophage-stem cell interactions either lead to removal of cytoplasmic material and stem cell proliferation or resulted in complete stem cell engulfment. Calreticulin knock down or embryonic macrophage depletion reduced the number of stem cell clones into adulthood. Our work supports a model in which embryonic macrophages determine hematopoietic clonality by monitoring stem cell quality.
Project description:In order to investigate the characteristics and mechanisms of embryonic stem cell derived exosomes attenuates transverse aortic constriction induced ventricular remodeling, the proteomic profiles of human embryonic stem cell derived exosomes were analysed by label-free quantification.
