Product Overview


Human astrocytes (HA) are derived from the human cerebral cortex. Astrocytes are the most abundant cells in the central nervous system, where they perform many functions, such as providing mechanical support and nutrition to neurons and removing waste from neurons. Provide signals to endothelial cells; regulate neurogenesis and control synaptic function. With the increasing understanding of the importance of astrocytes in the nervous system, HA has become a useful in vitro model for exploring the functional diversity of astrocytes.

Astrocyte; Primary Cell

Application Notes

Human Astrocytes from Creative Biolabs, Inc. have been used to:
• Investigate aberrant gene expression.
• Reveal that CBX6 overexpression inhibits proliferation of glyoblastoma cells and
• Demonstrate the role of epigenetics in glyioblastoma malignancy.
• Investigate choline uptake system in normal and glioblastoma cells with the hope to improve tomography imaging in glioblastoma patients

Cell Viability


Mycoplasma Testing

The cell line has been screened using the luciferase based mycoplasma detection kit to confirm the absence of mycoplasma species.

Sterility Testing

Sterility testing was performed in accordance with USP and EP regulations. All of our sterility testing is performed in an isolator or clean room environments. The cell line has been screened using the membrane filtration testing methods to confirm the absence of aerobic, anaerobic and fungi microorganisms.

Genetic Stability Testing

Cell genetic stability study was perfomed under ICH guidelines. We provide guidance on the appropriate testing program upon your requirements.

Handling Advice

Frozen cells: Upon receipt, frozen ampoules should be transferred directly to gaseous phase liquid nitrogen without delay, unless they are to be used straight away.

Growing cells: Growing cell cultures should be checked on receipt using an inverted microscope. Immediately check the cell density upon arrival for any obvious defects. If the cell density is too high (more than 80% confluent) subculture the cells (harvest and reseed) immediately.

For detailed instructions on the thawing procedure of frozen cells and the culture of adherent or suspended cells, please feel free to contact us by email or phone.

Research Use Only

Store under recommended storage conditions (liquid nitrogen). Do not expose to high temperature. After expiration, discard all remaining reagents. It is recommended to use cells within ten generations.

Quality Control
