Principles of Regulation of Self-Renewing Cell Lineages
Identifying the exact regulatory circuits that can stably maintain tissue homeostasis is critical for our basic understanding of multicellular organisms, and equally critical for identifying how tumors circumvent this regulation, thus providing targets for treatment. Despite great strides in the understanding of the molecular components of stem-cell regulation, the overall mechanisms orchestrat...
متن کاملa tripartite model of efl teachers attributions, burnout, and self-regulation: towards the prospects of effective teaching
همطالعه حاضر به ارائه مدلی برای آموزش موثر زبان انگلیسی می پردازد. مدل حاضر از سه عامل تاثیر گذار در کارایی تدریس معلمان زبان انگلیسی بهره می برد. این سه عامل شامل سبکهای اسنادی، خود تنطیمی و فرسودگی شغلی معلمان ایرانی زبان انگلیسی می باشد. رساله مورد نظر درچهار فاز طراحی شده است: فاز اول شامل طراحی و رواسازی پرسشنامه سبکهای اسنادی معلمان زبان انگلیسی و فاز دوم شامل استفاده از این پرسشنا...
Feedback regulation in multistage cell lineages.
Studies of developing and self-renewing tissues have shown that differentiated cell types are typically specified through the actions of multistage cell lineages. Such lineages commonly include a stem cell and multiple progenitor (transit amplifying; TA) cell stages, which ultimately give rise to terminally differentiated (TD) cells. In several cases, self-renewal and differentiation of stem an...
متن کاملRegulation of self-renewing neural progenitors by FGF/ERK signaling controls formation of the inferior colliculus.
The embryonic tectum displays an anteroposterior gradient in development and produces the superior colliculus and inferior colliculus. Studies suggest that partition of the tectum is controlled by different strengths and durations of FGF signals originated from the so-called isthmic organizer at the mid/hindbrain junction; however, the underlying mechanism is unclear. We show that deleting Ptpn...
متن کاملThe Rho-Rock-Myosin Signaling Axis Determines Cell-Cell Integrity of Self-Renewing Pluripotent Stem Cells
BACKGROUND Embryonic stem (ES) cells self-renew as coherent colonies in which cells maintain tight cell-cell contact. Although intercellular communications are essential to establish the basis of cell-specific identity, molecular mechanisms underlying intrinsic cell-cell interactions in ES cells at the signaling level remain underexplored. METHODOLOGY/PRINCIPAL FINDINGS Here we show that endo...
