background: the definitive endoderm (de) differentiation using the undefined media and non-human feeders can cause contaminations in the generated cells for therapeutic applications. therefore, generating safer and more appropriate de cells is needed. this study compared five different methods to establish an appropriate method for inducing an efficient de differentiation from human induced plu...

background:the zinc-finger x linked (zfx) gene encodes a transcription factor that acts as a regulator of self-renewal of stem cells. due to the role of zfx in cell growth, understanding zfx protein-protein interactions helps to clarify its proper biological functions in signaling pathways. the aim of this study is to define zfx protein-protein interactions and the role of zfx in cell growth. m...

objective: cd44+/cd24-/low breast cancer cells have tumour-initiating properties with stem cell-like features. breast cancer gene 1 (brca1) is a tumour suppressor gene that plays a crucial role in dna repair and maintenance of chromosome stability. the clinicopathological features of breast cancer in brca1 mutation carriers suggest that brca1 may function as a stem-cell regulator. materials and...

Introduction: Prostate cancer (PCa) is the most prevalent malignant tumor in the male population worldwide and it is the second leading cause of cancer-related death in males. PCa is almost incurable due to the resistance of PCa to conventional treatments. Cancer stem cells (CSCs) theory suggests that a small subpopulation of cancer cells is responsible for tumor development, ...

background: in cancer patients, chemo and radiotherapy can cause infertility by damaging spermatogenesis process. this process is based on self-renewal and differentiation of a rare population of the testicular cells called spermatogonial stem cells (sscs). scientists have tried to isolate, enrich and culture human spermatogonial stem cells, hoping to resolve infertility problems in cancer reco...

Cancer Stem Cells Microfluidic tumors-on-chips models have revolutionized anticancer therapeutic research by creating an ideal microenvironment for cancer cells. The current trend modeling stem cells in is discussed article number 2100017 Devrim Pesen-Okvur, Amir K. Miri, and co-workers. Opportunities the incorporation of with represent a paradigm shift community allowing clinicians to better p...

Differentiation is an epigenetic process which is installed by changes of transcriptional programs over successive cellular divisions. A number of studies have reported the effects of biochemical modifications of chromatin (DNA and chromatin proteins) on the regulation of transcription. Although, these studies are able to explain how transcription of a given gene is regulated (toward activation...

Background: With treatment success in young boys with cancer, long-term effects of cancer treatment have found importance in pediatric oncology. Temporary or permanent infertility after treatment is an important subject in childhood and adult cancer patients which decrease quality of life. The one approach to overcome infertility in these cases is to cryopreserve small biopsy testicular tissue ...
