[61] In a study published in a 2011 issue of Nature Biotechnology [62] a group of researchers from the University of Wisconsin reports that it has been able to direct embryonic and induced human stem cells to become astrocytes. 2012-02-29 · Background The tumor microenvironment contains normal, non-neoplastic cells that may contribute to tumor growth and maintenance. Within PDGF-driven murine gliomas, tumor-associated astrocytes (TAAs) are a large component of the tumor microenvironment. The function of non-neoplastic astrocytes in the glioma microenvironment has not been fully elucidated; moreover, the differences between these Differential modulation of ATP-induced calcium signalling by A1 and A2 adenosine receptors in cultured cortical astrocytes Susanna Alloisio IntroductionAdenine-based purines are ubiquitous extracellular signalling molecules, which in mammals are involved in the functional regulation of virtually all tissues and organs (Ralevic & Burnstock, 1998).

Finally, we show that A1 astrocytes are abundant in various human neurodegenerative In 2012, Barres and his colleagues resolved that ambiguity when they identified two distinct types of reactive astrocytes, which they called A1 and A2. In the presence of LPS, a component found in the cell walls of bacteria, they observed that resting astrocytes somehow wind up getting transformed into A1s, which are primed to produce large volumes of pro-inflammatory substances.


Clearly, A2 reactive astrocytes promote healing after ischemic injury (Sofroniew and Vinters, 2010). In ischemic stroke, on the other hand, astrocytes assume a helpful A2 state, and release neurotrophins.

2 The Barres lab continued to characterize these different astrocyte phenotypes. The border of A1/A2 was defined by dark field illumination, the results of which are depicted in Figure 3. To examine the density of astrocyte processes in the A1 vs. A2 cortex, we obtained ten bands 25 µm wide and 100 µm long, their centers located at the borders between A1/A2 (Figure 3C, middle). Thus, while defining these phenotypes is an important step, reactive astrocytes may also exceed the A1–A2 dichotomy and assume a range of profiles with mixed A1 and A2 features . It has been proposed that although reactive astrocytes share common properties, they also display unique cellular and molecular features that are specific to Recently, reactive astrocytes were further classified into A1 astrocytes and A2 astrocytes according to their functions.

We investigated whether STAT1 and STAT3 are essential for astrocyte development by testing the STAT responsiveness This video describes the structure and function of astrocytes.

As well as releasing a potent neurotoxin, A1 astrocytes were less able to promote the formation of new synapses, and caused a decrease in the excitatory function of … Recently, reactive astrocytes were separated into two types, A1 (cytotoxic) and A2 (neurotrophic). However, their role in prolonged cerebral hypoperfusion remains unclear.
