Accelerated Osteocyte Differentiation of Human Mesenchymal Stem Cells in a Novel Xeno-free and Serum-free Osteogenesis Differentiation Media
Mesenchymal stem cells (MSCs) have the capacity for multi-lineage differentiation, giving rise to a variety of mesenchymal phenotypes such as osteoblasts (bone), adipocytes (fat), and chondrocytes (c...

Common Cell Culture Problems: Cell Clumping
Cells in suspension may attach to one another and form clumps for a variety of reasons. The most common cause of cell clumping is the presence of free DNA and cell debris in the culture medium, which...

Common Cell Culture Problems: Cell Death
There is perhaps nothing more frustrating to a cell culturist than removing a dish from the incubator only to find that it’s full of dead cells. Getting to the bottom of the problem can be very chall...

Common Cell Culture Problems: Cell Line Cross-Contamination and Misidentification
A few years after scientists working at Johns Hopkins established the first human cell line using cervical epithelial cells (HeLa) from cancer patient Henrietta Lacks in the early 1950s, it was obser...

Common Cell Culture Problems: Poor Attachment of Adherent Cells
Optimal cell attachment in vitro requires the interaction of healthy cells with a wide range of cell-derived attachment molecules present in media, serum, and supplements. Cultureware surfaces are fr...

Common Cell Culture Problems: Precipitates
When contamination is ruled out, turbidity in cell culture media is often explained by the precipitation of metals, proteins, and other media components. Precipitates can be harmful to cell health, a...

Common Cell Culture Problems: Poor Cell Growth
Ensuring adequate cell growth is a critical part of collecting accurate data with cell cultures. Cells can be cultured in suspension, or as a monolayer that attaches to cultureware, such as a flask, ...

Resuscitation of Frozen Cell Lines
Many cultures obtained from a culture collection, such as ECACC, will arrive frozen and in order to use the cells they must be thawed and put into culture. It is vital to thaw cells correctly in orde...

Subculture of Adherent Cell Lines
Adherent cell lines will grow in vitro until they have covered the surface area available or the medium is depleted of nutrients. At this point the cell lines should be sub cultured in order to preve...

Subculture of Semi-Adherent Cell Lines
Some cultures grow as a mixed population (e.g. B95-8 - marmoset) where a proportion of cells do not attach to the tissue culture fl ask and remain in suspension. Therefore to maintain this heterogene...

Subculture of Suspension Cell Lines
In general terms cultures derived from blood (e.g. lymphocytes) grow in suspension. Cells may grow as single cells or in clumps (e.g. EBV transformed lymphoblastoid cell lines). For these types of ce...
