Ms. Michi is a researcher in a renowned pharmaceutical company based in Singapore. One of the cell lines in the lab is suspected to be contaminated. She is culturing NIH 3T3 mouse embryo fibroblast cell line (NIH/3T3 (ATCC® CRL-1658TM). Figure 1 below illustrates her observation under the inverted phase contrast microscope. a) b) c) d) e) Figure 1 (Routray et al., 2016) What type of contamination is her laboratory facing? Explain your answer. Give FOUR (4) suggestions to Michi in order to prevent such contamination in future Besides the contamination stated in Question 2 a), name FIVE (5) other contaminations that Michi should be aware of. During a routine check, Michi's superior requests her to characterize cell lines available in the storage to determine their authenticity. Describe TWO (2) effective cell line characterization methods that she can utilize for this purpose. The pharmaceutical company wants to improve its toxicity testing by replacing monolayer culture with spheroid culture system. Describe the advantages of spheroid culture.
