Answer:
Culturing human embryonic stem cells (hESCs) requires a significant commitment of time and resources. It takes weeks to establish a culture, and the cultures require daily attention. Once hESC cultures are established, they can, with skill and the methods described, be kept in continuous culture for many years.
I hope it's helpful for you.
Thank you.

Mouse embryonic stem (ES) cells are used to generate mouse mutants by gene targeting and blastocyst-mediated transgenesis. ES cells must be cultured under conditions that prevent differentiation to maintain their ability to transmit altered alleles by contributing to the germ line.
Explanation:How are ES cells obtained?
Human ES cell lines are derived from embryos produced by in vitro fertilization (IVF), a process in which oocytes and sperm are placed together to allow fertilization to take place in a culture dish.
What are human ES cells?
Embryonic stem cells (ES cells or ESCs) are pluripotent stem cells derived from the inner cell mass of a blastocyst, an early-stage pre-implantation embryo. Human embryos reach the blastocyst stage 4–5 days post fertilization, at which time they consist of 50–150 cells.
