Wharton’s Jelly is a soft, gelatinous tissue found inside the human umbilical cord. It contains a highly concentrated population of cells called mesenchymal stem cells (MSCs) that have been the subject of growing scientific interest over the past two decades. What makes them particularly relevant to cell-free research is not only the cells themselves, but also what they secrete: a complex mixture of proteins, growth factors, and extracellular vesicles that researchers study for their role in biological signaling. Cell-free approaches that work with this secreted material, rather than with live cells directly, represent one of the more active areas of current investigation in this field.

If you have been hearing a lot about exosomes and extracellular vesicles lately, you are not alone. These two terms are often used interchangeably, even though they are not quite the same thing. Extracellular vesicles (EVs) are tiny particles that cells release as part of normal biological communication. Exosomes are one specific type of EV, generally considered the smallest and most studied subtype. Understanding the difference between them is a useful starting point for anyone following the science of cell biology and regenerative medicine research.

Understanding the Body’s Natural Signaling Process The way we think about regenerative medicine is shifting. It’s not just about the cells anymore—it’s about their secret language of signaling. What the MSC Secretome Includes At NuvoCell Biologics, we’re closely following—and contributing to—a new wave of regenerative science that focuses not on the cells themselves, but on … Read more
