In Observance of a U.S. Holiday Agilent Cross Lab/ iLab Operations Software Support Help Desk will be closed during U.S. hours on Wednesday June 19th, 2024. We will resume regular U.S. support hours on Thursday June 20th, 2024. EU and APAC Support will remain open during this time. For urgent matters, please add "Urgent" to the ticket/ email subject or press "1", when prompted, to escalate a call on the iLab Support phone and we will prioritize those requests first.

UTSA Stem Cell Core


Overview of Services

The Stem Cell Core offers five basic services that function independently but can also be combined for larger projects.

  • Isolation and Cryopreservation of Cells from Adult Tissues: The Core isolates fibroblasts, PBMCs or other cell types from donor samples and cryopreserves these for future use.
  • Reprogramming of Adult Tissues to Induced Pluripotent Stem Cells: The Core receives samples from investigators and reprograms these using non-integrating vector systems resulting in footprint free iPSCs. These samples can be any cell type and we have successfully reprogrammed cells from multiple species including humans, non-human primates and mice. Additionally, we provide a full suite of quality control options to ensure that the iPSCs produced are of the highest quality.
  • Gene Editing of Pluripotent Stem Cells: The Core designs and carries out gene editing of pluripotent stem cells using CRISPR/CAS9. These services include, in silico design of guide RNAs and homologous damage repair templates, validation of enzymatic cutting efficiencies, transfection of reagents into the cells, clonal selection of modified cells and quality control for maintenance of the pluripotent phenotype.
  • Custom Research Utilizing Pluripotent Stem Cells and their Differentiated Progeny: The Core designs and carries out custom research for investigators who do not have the experience or the infrastructure necessary to complete these experiments. These involve production of 2D and 3D differentiated cells or testing of small molecules and other reagents for biological effect or toxicity.
  • Consultation and Training: The Core provides consultation on any area of pluripotent stem cell research and training in all technologies described above.
