the provision of an adequate quantity of cells with proper function and purity is one of the main challenges of tissue engineering studies. stem cells, with their self-renewal and differentiation capacity, are considered one of the main cell sources in the field of tissue engineering. previously, the use of chemical factors seemed to be the only possible way for stem cell differentiation. howev...

nowadays, scientific c findings in the field of regeneration of nervous system have revealed the possibility of stem cell based therapies for damaged brain tissue related disorders like stroke. furthermore, to achieve desirable outcomes from cellular therapies, one needs to monitor the migration, engraftment, viability, and also functional fate of transplanted stem cells. magnetic resonance ima...

context stem cells have the potential to generate a renewable source of cells for regenerative medicine due to their ability to self-renew and differentiate to various functional cell types of the adult organism. the extracellular microenvironment plays a pivotal role in controlling stem cell fate responses. therefore, identification of appropriate environmental stimuli that supports cellular p...

Stem Cell Lineage Fate Highly accurate, efficient, and convenient evaluation for biomaterial-induced stem cell lineage fate is pivotal regenerative biomaterials research. In article number 2210637, Binbin Lai, Xuehui Zhang, Xuliang Deng, co-workers report MeD-P, a machine-learning-supported intelligent model, predicting human mesenchymal cell–biomaterial interaction based on RNA-seq data. This ...

Several signaling pathways and transcription factors control the cell fate in its in vitro development and differentiation. The orchestrated use of these factors results in cell specification. In coculture methods, many of these factors secrete from host cells but control the process. Today, transcription factors required for retinal progenitor cells are well known, but the generation of these ...

neurotrauma is one of the main medical problems that affect considerable number of population especially young persons in all countries. neurotrauma not only is a serious threat for life but also creates various disabilities and consequently imposes large costs to society. following central nervous system (cns) injury, tissue damage occurs via primary and secondary mechanisms. despite many atte...

Identification of cell-fate determinants for directing stem cell differentiation remains a challenge. Moreover, little is known about how cell-fate determinants are regulated in functionally important subnetworks in large gene-regulatory networks (i.e., GRN motifs). Here we propose a model of stem cell differentiation in which cell-fate determinants work synergistically to determine different c...

Background: Cell viability and apoptosis are two crucial factors that may determine cell fate. There are several factors, such as hypoxia, which may be effective in cell processes. Because of its unique features, such as its antioxidant, anti-inflammatory, and anti-apoptosis mechanisms, kohlrabi (Brassica oleracea var. gongylodes) extract may be used in the amelioration of cell viability and a ...

Mitochondria are highly dynamic organelles that undergo cycles of fusion and fission important for their function, maintenance, and quality control as well as direct or indirect role in different types of stem cells fate decisions. Stem cells have potential for numerous biomedical applications; however the major bottle neck in stem cell field is the stem cell differentiation and maintenance of ...

Germline stem cells (GSCs) in Drosophila are a valuable model to explore of how adult stem cells are regulated in vivo. Genetic dissection of this system has shown that stem cell fate is determined and maintained by the stem cell's somatic microenvironment or niche. In Drosophila gonads, the stem cell niche -- the cap cell cluster in females and the hub in males -- acts as a signaling center to...
