What is the SanatelaTM Matrix?

Individualized medicine that is ready to go, right now

A Matrix is made from Wharton’s Jelly, the gelatinous connective tissue that surrounds and supports blood vessels in an umbilical cord. It contains an abundance of all the key components of the extracellular matrix, the three-dimensional network of proteins, enzymes and other macromolecules that provide structure and biochemical support to cells. It also contains a number of substances that stimulate cell growth and replication.

To bioengineer a Matrix, Wharton’s Jelly is first separated from an umbilical cord, then decellularized, homogenized, shaped and freeze-dried (lyophilized). The steps of this patented process vary depending on what the Matrix will be used for: screening cancer treatments, growing cells in a culture (including stem cells), regenerating tissue to treat defects and wounds, or forming complex tissues and organs.

The completed Matrix retains all of the key components of the extracellular matrix found in Wharton’s Jelly, uniformly distributed. The 3D structure is also maintained, enhanced by uniform pore size and distribution.

What can the Sanatela Matrix be used for?

The Matrix is a scaffold on which doctors and scientists can recreate natural environments found in the human body to support and expand any type of cell population, including stem cells. Cells of many types can be cultured in vitro on the Matrix.

The Matrix is currently being evaluated as a platform to screen cancer treatments, starting with leukemia. It is a 3-dimensional microenvironment that imitates the bone marrow “niche,” enabling and regulating the ability of Hematopoietic Stem and Progenitor Cells (HSPCs) to renew themselves. This novel in vitro culture system is based on Decellurized Wharton Jelly Matrix (DWJM) isolated and processed to form an extracellular matrix (ECM) scaffold. Researchers can then apply chemotherapies and other cancer treatments and test their effectiveness in an environment similar to bone marrow.

Leukemia stem cells are thought to support leukemia survival. They are an intense focus of research, but to study them researchers have to recreate the environment in which they live and function – the bone marrow (BM) hematopoietic “niche”. This niche also supports the HSPCs that are formed soon after conception, starting out in the yolk sac and eventually moving to the bone marrow of mammals, where it provides the protection and signals necessary to carry out the differentiation of normal blood cells.

The Matrix also provides structural and biochemical support to expand HSPCs like Umbilical Cord Blood (UCB) CD34+ cells, which seem to be attracted to the Matrix.

Amazingly, helping screen effective treatments for cancer is just one of many ways the Sanatela Matrix will make a transformative impact. Its ability to attract “normal” skin stem cells and give them the perfect environment to grow new tissue has many exciting medical applications.
