[Effect of the culture technic on the development of the hippocampus (rat) in vitro]
Abstract:
150 hippocampal explants from fetal and neonatal rats were cultivated with semisynthetic media in maximow chambers without movement and in roller tubes by rotation in the virutor up to 3 days. The cultures were fixed in Bouin, cuted 15 microns and coloured with the method of Klüver-Barrera or haemalaun. Histological examination of the explants revealed that hippocampi cultured in maximow chambers without movement possess an organisation similar to that observed in situ. Experiments with rotated explants of hippocampus indicate that the structure of hippocampus in vitro is changed. Especially neurons are degenerated and the migration of cells is altered. Finally the value of these two methodological cultivations for neurobiology is discussed.
Insights
Static culture methods preserve hippocampal explant organization, while rotation causes neuronal degeneration and altered cell migration. These findings impact neurobiology research techniques.
Area of Science:
- Neurobiology
- Histology
- Cell Culture
Context:
- Hippocampal explants are crucial for studying brain development and function.
- Understanding optimal culture conditions is vital for accurate in vitro research.
Purpose:
- To compare the structural integrity of hippocampal explants cultured using static (Maximow chamber) and dynamic (roller tube) methods.
- To assess the impact of different culture techniques on neuronal survival and cell migration.
Summary:
- Hippocampal explants cultured statically in Maximow chambers maintained in situ-like organization.
- Rotation in roller tubes led to significant neuronal degeneration and altered cell migration patterns.
- Histological analysis using Klüver-Barrera or haemalaun staining revealed structural differences.
Impact:
- Static culture methods are superior for preserving hippocampal structure in vitro.
- Dynamic culture methods may induce artifacts, affecting neurobiological interpretations.
- Findings guide the selection of appropriate methods for hippocampal research.
