Manufacturing Parameters for the Creation of Clinical-Grade Human-Induced Pluripotent Stem Cell Lines From Umbilical Cord Mesenchymal Stromal Cells.

Induced pluripotent stem cells (iPSCs) are reprogrammed cells with a remarkable capacity for unlimited expansion and differentiation into various cell types. Companies worldwide are actively engaged in developing clinical-grade iPSC lines to address the needs of regenerative medicine, immunotherapies, and precision medicine. However, ensuring the safety and quality of iPSCs is essential, with adherence to Good Manufacturing Practices (GMP) and ethical considerations being paramount.

A novel method to pack cryopreserved amniotic membrane for wound dressing-the pathway through validation of a new biological product.

Amniotic membrane (AM) has been widely used as a biological dressing for many pathologies and illnesses worldwide, and products derived from this tissue have been commercially available in several countries. In Brazil, regulatory agencies have recently authorized its clinical use as a non-experimental therapy for burns, diabetic and venous stasis ulcers, and intrauterine adhesions. In this study, we present our pathway through validating the first available service in the country of AM cryopreservation, with a protocol for long-term storage in high-efficiency nitrogen cryogenic freezers and a specific way of packing the tissue for optimal clinical handling and efficient storage space utilization while preserving live cells and the tissue's biological properties.

Relocating to a new facility: The challenge of a cord blood banking transferral in Brazil.

Background: Our cord blood banking facility planned and executed a transferral of its entire operation to a new site in the South of Brazil. Transporting LN2 freezers is a complex process in which extensive planning is essential to minimize the risks of damaging products or storage units.

Methods: To fulfill this objective, we constructed a detailed relocation plan consisting of four phases and risk mitigation measures, collaborated with the representatives of all departments, regulating agencies, and professionals from the transport company, and assembled a validation plan for cryogenic freezers and the viability of cord blood units.
