Cells Need Physiologic Simulation

In a typical incubator, cells experience controlled temperature and carbon dioxide levels. However, as we saw in the last post, cells can be out of optimum for long periods of time when handled in a room air biological safety cabinet (BSC).

There are many other factors that are critical for cells. The role of physiologic oxygen in cell culture should not be underestimated.

What is physiologic oxygen?

That depends upon the three L’s of physiology: Location, Location, Location

Cells Need Full Time Optimization

From a cell’s point of view in passive culture, at any one time it lives in one of four environments or states:

1. Incubation

2. Manual Manipulation (in biosafety cabinet, glove box, lab bench, etc…)

3. Machine Processing (centrifugation, mixing, flow cytometric sorting, etc…)

4. In Transport (between states 1, 2,or 3)

Cells Need Full Time Protection

The best environment for in vitro cell growth is also a favorable environment for microbial growth. Peoplecentric work environments include hoods, waterbaths and incubators that open into room air. In all of these spaces, cells and their culture vessels are exposed to airborne and people-borne contaminants.

What does it mean?

Cy·to·cen·tric, adj. 1. Taking the cells’ point of view in the laboratory and putting their needs first. Antonym.  Peoplecentric. Taking a person’s point of view in the laboratory and putting their needs first.

 

Cells cultured in vitro are critical to modern medical research across every subject area.

What do cells need outside of the body?

 

Think about what is in your lab and whether it is Cytocentric or Peoplecentric.

Do cells need the tables and chairs? Do cells need 21% oxygen?
