objective: nowadays, cord blood hematopoietic stem cells (hscs) are known as a valuable source for bone marrow transplantation but unfortunately their insufficient number is a limiting factor for using them in adult bone marrow transplantation. cord blood hcss expansion is an approach to overcome this problem, by inducing their self-renewal. tgf-b signaling pathway is a key inhibitory agent for...

Background: Any irregularities in self-renewal/differentiation balance in endometriotic MSCs can change their fate and function, resulting in endometriosis development. This study aimed to evaluate the expression of OCT4 transcripts (OCT4A, OCT4B, and OCT4B1), SOX2, and NANOG in endometriotic MSCs to show their aberrant expression and to support self-renewal/differentiation imbalance in these c...
nucleostemin (ns), a stem cell-abundant nucleolar protein, is critical for maintaining the self-renewal and proliferative properties of normal and cancerous stem cells. recent data suggests that ns signaling is important for proliferation of t-cells and leukemia cells. this study was conducted to verify the role of ns in pathogenesis and treatment of t-cell acute lymphocytic leukemia (t-all). o...
Self-renewal is the process by which stem cells divide to make more stem cells, perpetuating the stem cell pool throughout life. Self-renewal is division with maintenance of the undifferentiated state. This requires cell cycle control and often maintenance of multipotency or pluripotency, depending on the stem cell. Self-renewal programs involve networks that balance proto-oncogenes (promoting ...
objective(s):previous studies demonstrate that changes in pre-mrna splicing play a significant role in human disease development. furthermore, many cancer-associated genes are regulated by alternative splicing. there are mounting evidences that splice variants which express predominantly in tumors, have clear diagnostic value and may provide potential drug targets. located on the x chromosome, ...
Urban renewal and sustainable development are two popular issues in both policy agenda and academia. Although their importance has been increasingly recognized, an integrated review covering sustainability, planning, and urban renewal has yet to be produced. Based on 81 journal papers, this paper presents a critical review of recent studies on sustainable urban renewal over the period 1990 to 2...
