چکیده

Temporal sequences of transcription factors (tTFs) in Drosophila neural progenitors generate neuronal diversity. Mattar et al. (2015) identify Casz1/Castor as a late temporal identity factor in mouse retinal progenitors that is regulated by the early factor Ikzf1/Hunchback, thus generalizing the notion of tTFs.

Neuronal Diversification in the Postembryonic Drosophila Brain: A Dissertation

A functional central nervous system (CNS) is composed of numerous types of neurons. Neurons are derived from a limited number of multipotent neural stem cells. Previous studies have suggested three major strategies nature uses to diversify neurons: lineage identity specification that gives an individual neural stem cell distinct identity based on its position in the developing CNS; temporal ide...

Developing Nervous System

■ Abstract The nervous system of higher organisms exhibits extraordinary cellular diversity owing to complex spatial and temporal patterning mechanisms. The role of spatial patterning in generating neuronal diversity is well known; here we discuss how neural progenitors change over time to contribute to cell diversity within the central nervous system (CNS). We focus on five model systems: the ...

Neuroprotective Effects of Aqueous Extract of Achillea Wilhelmsii on Motor Neuron Destruction of Spinal Cord Ventral Horn after Sciatic Nerve Compression in Male Adult Rats

Background & Aims: Peripheral nerve injuries affect both sensory and motor function, resulting in retrograde reaction to neuronal cell bodies in the ventral horn of spinal cord ventral and their destruction. Achillea wilhelmsii is one of the popular medicinal herbs which grow in dry and semitropical areas worldwide. There are several reports indicating the anti-inflammatory, antispasmodic, anti...

مطالعه اثرات فراکسیون‌های ان‌بوتانول و اتیل استات گیاه سیاه‌دانه (Nigella sativa) بر دانسیته نورون‌های حرکتی شاخ قدامی نخاع بعد از ضایعه کمپرسیون عصب سیاتیک موش صحرایی

Introduction: Sciatic nerve compression is one of the factors that may cause the cell body degeneration of the alpha-motoneurons of spinal cord ventral horn. Nigella sativa belongs to the family of Ranunculaceae which owns numerous pharmacological properties. Therefore, this study was conducted to determine the neuro-protective effects of n-butanol and ethyl acetate fractions of Nigella sativa ...

اثرات محافظت نورونی عصاره الکلی درمنه بر دژنراسیون نورون‌های حرکتی شاخ قدامی نخاع به دنبال کمپرسیون عصب سیاتیک در موش صحرایی

Background and Aim: Peripheral nerve injury occurs in about 3% of the patients suffering from trauma and accidents. This injury induces Wallerian degeneration in the site of injury and, as a retrograde reaction, extends to the cell bodies of injured neurons in the central nervous system. The present study aimed to assess the neuro-protective effects of the alcoholic extract of Artemisia herba-a...
