As the experience of the centers increase and the mechanisms of immune alloreactivity are elucidated, authors believe that the success in this field will be enhanced.
Another important distinction is that newborn stem cells exhibit reduced alloreactivity and require less stringent human lymphocyte antigen (HLA) matching in traditional transplant applications than adult stem cells derived from other sources such as bone marrow.

It is therefore crucial to develop tools that enable monitoring of T-cell alloreactivity over time.
According to the company, the panel of reactive T cells (PRT) test assesses a solid organ transplant candidate's T cell response to foreign tissue, referred to as alloreactivity, the body's reaction to foreign tissue.
