Dr. Honaramooz's research interests are in reproductive biology and technology, with emphasis on spermatogenesis and male germline stem cells (i.e., gonocytes and spermatogonial stem cells). 

Honaramooz and colleagues have introduced several novel in vitro and in vivo models which have allowed breakthrough advances in the study and manipulation of testis cells and tissue. These models have also opened new avenues of research in male reproduction with widespread basic and applied applications (sample research stories, link, link, link, link, link).

For instance, his research has led to the introduction of a system for ‘germ cell transplantation’ in farm animals, a procedure in which testis cells are harvested from a fertile donor male and microinjected into the seminiferous tubules of an infertile recipient. This enables the recipient to become fertile and pass on the donor-derived or genetically-modified traits onto progeny. This has resulted in the production of world’s first transgenic farm animals using this new technology. This innovative system can be a faster, more efficient, and less-costly approach than cloning for production of transgenic farm animals. 

Another innovate model developed by Honaramooz and colleagues is ‘testis tissue xenografting’, a model system in which small fragments of testicular tissue from a newborn donor animal of almost any mammalian species can be grafted under the back skin of recipient mice. This in vivo culture system allows the progression of testicular tissue development from a neonatal state to full maturity and spermatogenesis. Using this system, it has now become feasible to produce sperm even from newborn mice, cats, dogs, sheep, goat, pig, cattle, horses, deer, bison, or monkeys, all in a host mouse. Therefore, testis tissue xenografting has opened new possibilities for research in reproductive biology and technology. This includes its use as a novel tool for the study and manipulation of spermatogenesis in different species, the conservation of valuable immature individuals such as endangered species and prized farm animals, and the potential preservation of fertility in prepubertal boys who are cancer patients undergoing gonadotoxic treatments.

Honaramooz and colleagues have also established a ‘testis tissue regeneration model’ (otherwise known as the ‘testis cell-aggregate implantation’ model). They demonstrated that isolated testis cells have an unexpected innate ability to form a completely new testis tissue again. This was achieved by enzymatic digestion of neonatal pig or sheep testis tissue to obtain fully dispersed testis cells, followed by centrifugation to form a cell aggregate, and implantation of the cell aggregate under the back skin of recipient mice. The host mouse acts as an in vivo incubator to allow rapid self-organization of the implanted cells into a structurally accurate and functionally competent pig or sheep regenerated testis tissue. This unique in vivo system provides an ideal model for the study and manipulation of testis factors involved in testis formation which naturally only occurs in the embryos and hence is inherently difficult to study. 

His research has also led to the introduction of novel and effective approaches for isolation, enrichment, culture, cryopreservation, characterization, genetic manipulation, and transplantation of spermatogonial stem cells or their progenitors (gonocytes).
