Behind the Hype: What You Need to Know About Placental Tissue Storage

The placenta is a remarkable organ that plays a vital role in nourishing and supporting the development of a baby throughout pregnancy its uniquely composed of both maternal and fetal tissues and serves as a biological bridge, facilitating the exchange of oxygen, nutrients, and waste between mother and child.

Due to its rich supply of stem cells from both maternal and fetal origins, the placenta has recently gained attention as a potential resource for future medical use. In response, some private cord blood banks have begun offering services to store placental tissue a development that raises several important questions:

In this post will explores the practical applications and current scientific landscape surrounding placental tissue storage.

What Is Placental Tissue Made Of?

As well known the placenta comprises both fetal and maternal components the fetal side includes structures like the umbilical cord, amnion, and chorion, while the maternal side is known as the decidua basalis the maternal portion delivers oxygen and nutrients and removes waste products via the umbilical cord vessels. Although umbilical cord tissue is rich in fetal stem cells, placental tissue contains a mix of maternal and fetal cells, which introduces complexity in its isolation and potential therapeutic use.

The Role of Stem Cells in Therapy

Among various types of stem cells, mesenchymal stem cells (MSCs) are the most widely researched for clinical and regenerative therapies. MSCs can be harvested from several sources: adipose tissue, bone marrow, umbilical cord tissue, and placenta. However, not all MSCs are created equal. Numerous studies favor MSCs derived from umbilical cord tissue, citing advantages such as:

Furthermore, umbilical cord tissue has been found to yield a significantly higher number of MSCs compared to other perinatal tissues, including the placenta.

Current State of Clinical Research

An analysis of the clinicaltrials.gov database reveals umbilical cord-derived MSCs are the focus of ten times more clinical trials than placental tissue-derived cells. This trend reflects the greater scientific and clinical confidence in cord tissue’s therapeutic potential. These cells have been studied for use in conditions such as:

In contrast, placental tissue studies are limited and often group multiple perinatal tissues together, making it difficult to isolate the specific contributions of placental cells. A significant challenge with placental tissue collection is ensuring sterility, which is more readily achieved when collecting umbilical cord tissue.

Regulatory and Practical Limitations

The extraction of stem cells from placental tissue needs using enzymatic, chemical, or mechanical dissociation techniques where Under existing FDA regulations, any stem cell or tissue product intended for personal, or family use must be:

Placental stem cells do not meet these criteria, and are therefore classified as investigational, unlicensed drugs. As a result, they can only be used in approved clinical trials, not for routine therapeutic applications.

Final Thoughts: Is Placental Tissue Storage Worth It?

Despite its biological richness, placental tissue storage currently lacks strong clinical evidence to justify its routine use. The science supporting umbilical cord tissue-derived stem cells is far more advanced, with significantly more research, regulatory clarity, and therapeutic potential. While future breakthroughs may expand the role of placental cells in medicine, as of now, storing placental tissue is a speculative investment. Families considering this option should weigh the cost against the uncertain clinical benefits and consult with medical professionals for guidance.
