Cell culturing of Cell Line HEK-293T

This is a brief lab report for a cell culture lab we performed over a few days of cell line Human Embryonic Kidney cells clone 293 T-antigen. Included 3 materials are the procedure we followed and the professor’s lab report format/rubric (REVIEW included notes), my results in spreadsheet, and a official lab manual for a citation source. Will NEED one additional cited source about HEK-293T.
I am mainly concerned about the Abstract, Introduction, and Discussion. I will review what you come up with and make some modifications of my own if need be.
