Astrocytes are one of the most important key players in the central nervous system CNS. Here, we are reporting a practical method of sexed hippocampal astrocyte culture protocol in order to study the mechanisms underlying the astrocyte function in male and female neonate pups after in-vitro ischemia. Recent clinical studies indicate that the severity of brain injury appear to be sex dependent, and that the male neonates are more susceptible to the effects of HI-related brain injury, resulting in more severe neurological outcomes as compared to females with comparable brain injuries. The development of reliable methods to isolate and maintain highly enriched populations of sexed hippocampal astrocytes is essential to understand the cellular basis of sex differences in the pathological consequences of neonatal HI. In this study, Seks Ve Ölüm Ps describe a method for creating sex specific hippocampal astrocyte cultures that are subjected to a model of in-vitro ischemia, oxygen-glucose deprivation, followed by reoxygenation. This method provides a useful tool to study the role of male and female hippocampal astrocytes following neonatal HI, separately. Growing body of evidence indicates that the roles of astrocytes are more than providing neuronal support. In fact, the roles of astrocytes under physiological conditions can be very complex, such as guiding the migration of the developing axons 1regulating CNS blood flow 2maintaining the pH homeostasis of the synaptic interstitial fluid 3and participating in the blood brain barrier 4 and synaptic transmission 5. Under pathological conditions, astrocytes respond to injury with a process called reactive astrogliosis in which the morphology, number, location, topography with respect to distance from insult and function of the astrocytes may change in a heterogeneous way 6,7. Astrogliosis seen following neonatal hypoxic ischemic encephalopathy maybe contributing to the morbidity and mortality of neonates 8. Although the localization of the injury depends on the gestational age and the duration Seks Ve Ölüm Ps the severity of the insult, hippocampus is one of the most commonly effected regions in the CNS after term neonatal HI, and increased hippocampal astrogliosis has been confirmed by up-regulation of the Glial Fibrillary Acidic Protein GFAP 3 d after the neonatal HI 7,10,12, Sex differences in astrocyte function were shown in both neonates and adult rodents after cerebral ischemia 14, In addition, male astrocytic susceptibility to in-vitro ischemia was shown by increased cell death compared to female cortical astrocytes in culture Sex differences start in-utero and continue until death Over the last decade, the importance of including the sexes in experimental conditions in cell culture and in-vivo studies have been the emphasis of the Institute of Medicine and NIH to seek fundamental knowledge in the sex differences seen in physiological and pathological conditions 17, Development of reliable methods to isolate and maintain populations of sexed hippocampal astrocytes is essential to understand the cellular basis of sex differences in the pathological consequences of neonatal HI. This technique can be used to test any hypothesis pertaining to hippocampal astrocytes in neonatal males and females under normoxic and ischemic conditions. Primary Astrocyte Culture protocol that is presented here is adopted from the protocols presented by Zhang Y 19 et al. Understanding the roles of sexed astrocyte functions under physiologic or pathophysiological conditions have been immensely elucidated by culturing these cells under in vitro conditions. The important aspect of performing sexed culturing is to determine the sex of the mouse pup prior to its use. We determined the sex of the mouse genetically by PCR and by visual assessment Figure 2 The methodology of sex determination using PCR was adopted with modifications from McClive and Sinclair, is quick, simple, and highly reproducible method Figure 2A shows the representative results of sex determination using PCR. The reaction includes multiplexed primer pairs for Sry and Myog genes that generate male specific bands of bp and female specific bands of bp, respectively. Visual determination of neonatal Seks Ve Ölüm Ps 1 — 3 mouse sex with naked eye was established by looking for the presence of small darkened spot between anogenital openings only in males Figure 2B 16, Although, culturing of astrocytes is convenient and relatively easy to establish under laboratory set up, this advantage can be hindered by its contamination primarily with microglia or neurons to a lesser extent. Contamination of the astrocytes can be easily determined by immunolabeling of the cultured cells with cell specific markers for either microglia IBA1 or neurons MAP2. On the contrary, none of the cells were found to express MAP2 suggesting the culture was totally devoid of any neuronal contamination Figure 3. Astrocytes possess a specific cytoarchitecture that allow them to respond to changes in their microenvironment including hypoxia. Immunocytochemical staining of sexed hippocampal cultured astrocytes with GFAP or SB mature astrocyte marker resulted in a highly selective and reproducible staining pattern Figure 5. GFAP and SB were colocalized in the cytoplasm and cell bodies of astrocytes, characterizing a matured astrocytic developmental stage where these cells tend to lose their Neural Stem Cell NSC potential Under normoxic conditions, hippocampal astrocytes presented a polygonal to fusiform and flat morphology [ Figure 5A, B normoxia 60X; arrow ], as evaluated using confocal microscopy. Figure 1. Decapitate pup to remove the head. Using fine scissors, make a Seks Ve Ölüm Ps incision of the skin, posterior to anterior, and peel back the skin with the help of a flat-tip forceps. Make a small incision at the base of the skull. Cut the skull along the midline and peel away two halves to expose the brain. Remove cerebellum with the help of a curved forceps. Carefully remove brain from the cranium and place into a sterile Petri dish. Flip the brain so that the ventral surface of the brain is facing up using a curved forceps, then separate both hemispheres with a sharp sterile surgical blade. Remove the bulging midbrain and thalamic tissue leaving the intact underlying hemisphere and revealing the hippocampus. Remove the hippocampus small C-shaped structure. Immediately place the hippocampal lobes obtained from both of the hemispheres in a separate Petri dish containing sterile HBSS. Please click here to view a larger version of this figure. Figure 2.
