Fig. 1. Mouse egg culture. The image shows the dish in which embryos are cultured and the progression of two-cell embryos to a hollow structure known as the blastocyst.[9]Fig. 1. Mouse egg culture. The image shows the dish in which embryos are cultured and the progression of two-cell embryos to a hollow structure known as the blastocyst.[9]Fig. 2. Chimeric mouse. This mouse resulted from a blastocyst, which normally would produce a white mouse, that was injected with teratocarcinoma cells from a brown mouse. The dark stripes on the mouse represent the contribution of the foreign brown-type cells.[11]Fig. 2. Chimeric mouse.

The small mouse is of normal size, and the large mouse resulted from a fertilized egg injected with a growth hormone gene, as shown in figure 3 above. The injected egg was transferred to a foster mother uterus and subsequently produced the large mouse which grew twice as fast and became 50% larger.[12]Fig. 4.

New gene being injected into fertilized mouse egg. The top image is a fertilized mouse egg before injection, and the bottom image is the egg following introduction of a solution containing a new gene (note the swollen pro-nuclear structure in the lower egg, which contains the chromosomes of the egg and the new gene).[13]Fig. 3.

Top panel. Recipient mouse testis that was injected with genetically modified spermatogonial stem cells containing a reporter transgene for Green Fluorescent Protein (GFP), which will fluoresce green. Bottom Panel. The testis will produce spermatozoa that transmitted the GFP transgene to offspring.[20]Fig. 5. Top panel.

The proposed clinical application of human spermatogonial stem cells (SSCs). Before treatment for cancer by chemotherapy or irradiation, a prepubertal boy could undergo a testicular biopsy to recover SSCs. The SSCs would be cryopreserved and/or cultured to expand their number in vitro. After treatment, the SSCs would be transplanted to the patient's testes to produce spermatozoa. A step for genetic correction to rescue a genetic disorder is possible prior to transplantation.[21]Fig. 6. Male germline stem cell transplantation.
