Welcome Our Special Specialist


Oscar Molina is the new Biorepository Specialist working within the Advanced Diagnostics laboratory. While he is new addition to the research team, Oscar is not new to Children's Medical Center as he previously worked within the core lab for five years starting in 2011. As the bio-repository specialist, Oscar will oversee the daily operational and administrative duties governing the Pediatric Bio-specimen Repository (PBR) program that is established here at Children's Medical Center.

Under the direction of Dr. Dinesh Rakheja, Chief of Pediatric Pathology, the bio-repository was created to further the research endeavors of researchers at Children’s Health System of Texas as well as other institutions by providing archival pathology samples, including tissue, blood, bone marrow, and other fluids.

Oscar’s team is currently incorporating new bio-banking software within OpenSpecimen® which will allow our bio-repository to grow on both a local and national level. Oscar states, “…he looks forward to both the challenges and emerging opportunities to come while working with you, the research team members here at Children’s, and I hope to make a positive impact for our patients.”  Please join me in welcoming Oscar Molina!

More about the Biorepository:

This program was created to enable the further development of basic and translational oncology research programs within various departments at Children’s Medical Center Dallas, the University of Texas Southwestern Medical Center, and other institutions. It is a voluntary, non-profit activity supported by Children’s Medical Center and the University of Texas.

The repository contains a variety of frozen tissue samples from patients who underwent surgery at Children’s Medical Center and gave permission for the excess tissue not required for diagnostic purposes to be used in research studies. It also includes a number of unique cell lines developed from malignancies as well as archived paraffin embedded tissue from the diagnostic files of the department of Pathology. A database catalogs the available tissue and some clinical information. Samples are released to researchers in a de-identified manner to protect the identity of the patient.

Tissue is available at no cost to researchers for studies that have been approved by an appropriate Institutional Review Board and following approval by the Tissue Repository Utilization Committee, if appropriate. This committee is composed of physician and physician scientists who care for Children’s patients and conduct research on pediatric disorders.  Once the Pediatric Bio-specimen Repository Request for Tissue form has been submitted, it will be distributed to the Tissue Repository Utilization Committee, and a decision will be rendered within 1-2 weeks.
