DNA methylation analysis identifies key transcription factors involved in mesenchymal stem cell osteogenic differentiation

Biol. Res; 56 (), 2023
BACKGROUND: Knowledge about regulating transcription factors (TFs) for osteoblastogenesis from mesenchymal stem cells (MSCs) is limited. Therefore, we investigated the relationship between genomic regions subject to DNA-methylation changes during osteoblastogenesis and the TFs known to directly interact ...

Smad1/5 signal transduction regulates the ameloblastic differentiation of induced pluripotent stem cells

Abstract Induced pluripotent stem (iPS) cells could be induced into ameloblast-like cells by ameloblasts serum-free conditioned medium (ASF-CM), and bone morphogenetic proteins (BMPs) might be essential during the regulation of this process. The present study investigates the signal transduction that reg...

Proliferation and differentiation of mouse spermatogonial stem cells on a three-dimensional surface composed of PCL/gel nanofibers

Int. j. morphol; 37 (3), 2019
Spermatogonial stem cells (SSCs) have self-renewal and differentiation capacity essential for sperm production throughout the male reproductive life. The electrospun polycaprolactone/gelatin (PCL/Gel) nanofibrous scaffold mimics important features of the extracellular matrix (ECM), which can provide a pr...

Functional disruption of human leukocyte antigen II in human embryonic stem cell

Biol. Res; 48 (), 2015
BACKGROUND: Theoretically human embryonic stem cells (hESCs) have the capacity to self-renew and differentiate into all human cell types. Therefore, the greatest promise of hESCs-based therapy is to replace the damaged tissues of patients suffering from traumatic or degenerative diseases by the exact sam...

Mecanismos de ação da bradicinina na diferenciação neural in vitro

Durante o desenvolvimento do sistema nervoso, as células têm a tarefa de proliferar, migrar, diferenciar, morrer ou amadurecer de modo altamente preciso para formar estruturas complexas. Tal precisão é alcançada em decorrência da interação perfeita entre as células que se comunicam por meio de m...

Fosfoproteômica e proteômica quantitativa de células mesenquimais durante a diferenciação osteoblástica mediada por BMP2, expressão e purificação de diferentes tipos de proteínas morfogenéticas ósseas

As fraturas e perdas ósseas representam altos riscos para o Sistema público de Saúde (SUS), além de afetar a qualidade de vida do paciente, portanto é necessário o entendimento das bases moleculares que envolvem os mecanismos de reparo ósseo. Citocinas secretadas por células do sistema imune pres...
