That cross-contaminations of HeLa are still a major ongoing problem with modern cell cultures not with your cells, exactly. If you have had a transplant of tissues that involve HeLa cell lines, you will not see these on your skin.
Hela cells were remarkable because they grew in culture, doubled every 24 hours and they didn't die.
I don't really know the answer to this question, but each cell does affect what the plant does and how it does it.

the rhinovirus duplicates only in higher primates such as humans...
Hela cell is about 14um each in size. Steven x
it is an immortal cell
A HeLa cell is an animal cell, or more specifically, a human cell. This immortal cell line was taken from a patient named Henrietta Lacks. See related link

Hela cells were remarkable because they grew in culture, doubled every 24 hours and they didn't die.
Human epidermoid cancer cells (Hep-2) or (HEp-2) are now known to be HeLa contaminated. The Hep-2 cell line was derived from a male cancer patient but the Hep-2 cells available now show clear signs of HeLa contamination. This cell-line lacks a Y chromosome and has a number of markers associated with HeLa cells. ATCC lists HEp-2 as a misidentified cell line. Other mouth and throat cancer cell lines are available from ATCC and other repositories. Those lines do not contain cervical cancer cells.

Well, consider the HeLa cells, which have been studied for decades to help scientists understand cell processes.
Research has shown that HeLa cells have an active form of the enzyme Telomerase (not present in normal cells, but can be found in most cancerous cells). Telomerase is active during cell division, and prevents the shortening of telomeres - a mechanism that is associated with ageing and eventual cell death.
Well, Hela cells are basically immortal cell line . They will keep growing if they are provided with appropriate media (e.g DMEM,10 % FCS/FBS & antibiotic). Moreover , you should also check for the cellular confluence, if its higher than 90 % then your cells start to die and you need to harvest them again.
