Regenerative Potential of Menstrual Blood Stem Cells


Recent research has uncovered the regenerative capabilities of stem cells found in menstrual blood, marking a significant breakthrough that stems from studies conducted over the past two decades. This revelation not only expands our understanding of the intricate dynamics between the female reproductive system and regenerative processes but also opens new frontiers in reproductive health.

  1. Menstrual Blood Stem Cells (MenSCs)
  2. Challenges in Menstrual Stem Cell Research

Menstrual Blood Stem Cells (MenSCs):


  • Also known as endometrial stromal mesenchymal stem cells.
  • Exhibit multipotent properties, capable of differentiating into various tissue types (e.g., fat cells, bone cells, smooth muscle cells).

Ethical Source:

  • Considered an ethical source of adult stem cells.
  • Painlessly collected from women, offering an alternative to surgical biopsies.
  • Collected through a menstrual cup, providing a non-invasive method.

Collection and Origin:

  • Derived from menstrual blood, specifically from the endometrium (lining inside the uterus).
Role in Women’s Health:

Multipotent Characteristics:

  • MenSCs can differentiate into neurons, cartilage, fat, bone, heart, liver, and skin cells.

Potential Therapeutic Applications:

  • Treatment of gynaecological disorders like endometriosis and infertility.
  • Endometriosis Overview:
    • Disease where tissue similar to the uterine lining grows outside the uterus.
    • Symptoms include pelvic pain, painful intercourse, infertility, heavy menstrual bleeding, and gastrointestinal issues.
    • MenSCs play a role as the backflow of menstrual blood contributes to endometriosis.

Beyond Gynaecological Diseases:

  • Diabetes Treatment:
    • Injection of MenSCs in diabetic mice stimulated the regeneration of insulin-producing cells, improving blood sugar levels.
  • Wound Healing:
    • Menstrual stem cells or their secretions applied to injuries aided wound healing in mice.

Transplantation in Humans:

  • Menstrual stem cells can be transplanted into humans without adverse side effects, indicating their potential in regenerative medicine.

Challenges in Menstrual Stem Cell Research

Limited Research Share:

  • Despite the convenience of collection, menstrual stem cell research is a minute fraction of overall stem cell research.
  • As of 2020, menstrual stem cell research comprised only 0.25% of all mesenchymal cell research, whereas bone marrow stem cells represented a significant share at 47.7%.

Consistent and Scalable Production:

  • Ensuring consistent and scalable production of MenSCs for clinical applications poses a challenge.
  • Achieving standardized methods for production is vital to harness the full potential of MenSCs in regenerative medicine.

Cultural Taboos and Limited Investment:

  • Cultural taboos surrounding menstruation contribute to limited investment in women’s health research.
  • Securing funding for menstrual stem cell studies faces challenges due to societal attitudes and perceptions.

Gender Bias in Research Funding:

  • Addressing gender bias in research funding is crucial for advancing menstrual stem cell research.
  • Overcoming stereotypes and biases associated with women’s health is necessary to recognize and develop the promising applications of menstrual stem cells in regenerative medicine.
