Abstract

Insights

Assisted reproductive technologies (ARTs) are established for Japanese field voles (Microtus montebelli) but not for other Microtus species. Further development is needed to expand ART applications in this genus for research models.

Area of Science:

  • Reproductive biology
  • Animal models
  • Genetics

Background:

  • The Microtus genus, including the Japanese field vole (Microtus montebelli), possesses unique characteristics making it valuable for research.
  • Advancing the utilization of Microtus species as research models hinges on the development of assisted reproductive technologies (ARTs).

Purpose of the Study:

  • To review recent advancements in the development of ARTs for the Microtus genus.
  • To specifically highlight progress in ARTs for Microtus montebelli.

Main Methods:

  • A comprehensive review of existing literature and original publications.
  • Summarization of the current status of ART development within the Microtus genus.

Main Results:

  • ARTs, including superovulation, in vitro fertilization, intracytoplasmic sperm injection, embryo transfer, sperm cryopreservation, and artificial insemination, are well-established in M. montebelli.
  • ART protocols developed for M. montebelli were largely ineffective for Microtus arvalis and Microtus rossiaemeridionalis, with the exception of sperm cryopreservation.

Conclusions:

  • Established ARTs in M. montebelli enhance its potential as a model organism.
  • ART protocols require species-specific optimization for broader application across the Microtus genus, as current methods are not universally transferable.

Reproductive Cloning01:27

Reproductive Cloning

Reproductive cloning is the process of producing a genetically identical copy—a clone—of an entire organism. While clones can be produced by splitting an early embryo—similar to what happens naturally with identical twins—cloning of adult animals is usually done by a process called somatic cell nuclear transfer (SCNT).
Somatic Cell Nuclear Transfer
In SCNT, an egg cell is taken from an animal and its nucleus is removed, creating an enucleated egg. Then a somatic...

Overview of the Reproductive System01:31

Overview of the Reproductive System

The reproductive system generates offspring, ensuring the survival of the species. In humans, the reproductive system is complex and involves a variety of organs and hormones that work together to ensure successful reproduction.
The gonads, or primary reproductive organs, produce gametes and sex hormones. In males, the testes produce spermatozoa and testosterone, which is responsible for developing secondary male sex characteristics, including a deeper voice, larger muscles, facial and body...

Asexual Reproduction02:38

Asexual Reproduction

Asexual reproduction allows plants to reproduce without growing flowers, attracting pollinators, or dispersing seeds. Offspring are genetically identical to the parent and produced without the fusion of male and female gametes.

Disorders of the Female Reproductive System01:24

Disorders of the Female Reproductive System

The female reproductive system can be affected by several disorders, including Premenstrual Syndrome (PMS), Premenstrual Dysphoric Disorder (PMDD), endometriosis, and various forms of cancer. PMS and PMDD are cyclical conditions that cause physical and emotional distress, with symptoms that include edema, mood swings, and food cravings. PMDD is a more severe form of PMS characterized by increased symptom severity that peaks during the luteal phase and tends to improve or resolve shortly after...

Disorders of the Male Reproductive System

Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra....

Hybridoma Technology01:31

Hybridoma Technology

Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or epitope. Such antibodies are used in research, diagnostics, and disease therapy. The hybridoma technology established in 1975 by Georges Köhler and Cesar Milstein was awarded the Nobel Prize in Medicine in 1984 for revolutionizing research and therapy.
