%X Polyploid giant cancer cells (PGCCs) play a fundamental role in tumor initiation, dormancy, drug resistance, and metastasis, although the detailed biology of PGCCs remains poorly understood. The lack of literature on establishing a reproducible in vitro system for generating PGCCs is the leading technological obstacle to studying the biology of PGCCs. Here we provide a detailed protocol for generating stable PGCCs from Hey cancer cells and studying the PGCCs' embryonic stemness. This protocol includes (1) generating PGCCs of high purity in 2D culture by exposing Hey cells to paclitaxel, monitoring the cell cycle and amitotic budding of daughter cells from PGCCs, and collecting and studying the daughter cells; (2) inducing PGCCs to form spheroids expressing embryonic stemness markers and observing the spheroids' cleavage and blastocyst-like structure; and (3) inducing redifferentiation of PGCCs into different lineages of differentiated cells.
