[1] c-Myc, KLF4, Oct4, Sox2 and possibly others could transform cells, via retroviral/adenoviral/plasmid, into ES-like stem cells (iPSC), enabling experimentation in these cell lines. [2] Cell lines. Manipulation of cells' genotype by introducing specific SNPs and consequent observation. [3] Can be studied for apoptosis, tumor formation etc. [4] Of uncertain yield. [0] 
Transcription factors I strongly suggest this is not qualified as a technical approach
