Cell Banking of hiPSCs: A Practical Guide to Cryopreservation and Quality Control in Basic Research

The reproducibility of stem cell research relies on the constant availability of quality-controlled cells. As the quality of human induced pluripotent stem cells (hiPSCs) can deteriorate in the course of a few passages, cell banking is key to achieve consistent results and low batch-to-batch variation. Here, we provide a cost-efficient route to generate master and working cell banks for basic research projects. In addition, we describe minimal protocols for quality assurance including tests for sterility, viability, pluripotency, and genetic integrity. © 2020 The Authors. Basic Protocol 1: Expansion of hiPSCs Basic Protocol 2: Cell banking of hiPSCs Support Protocol 1: Pluripotency assessment by flow cytometry Support Protocol 2: Thawing control: Viability and sterility Support Protocol 3: Potency, viral clearance, and pluripotency: Spontaneous differentiation and qRT-PCR Support Protocol 4: Identity: Short tandem repeat analysis.

The economic cost of illness in the Federal Republic of Germany in the year 1980

This paper provides an empirical investigation of the economic cost of illness, disability and premature death in the Federal Republic of Germany in the year 1980. Direct and indirect cost of morbidity and mortality are estimated and allocated to the disease categories of the ICD-International Classification of Diseases. Against the background of increasingly scarce resources in health care, the findings of cost of illness studies obtain special significance for the setting of priorities for the allocation of these resources. In comparison to the status quo, a disease-oriented approach may provide a more differentiated and national basis for the ex-ante macro-allocation of health care resources as well as for the identification of areas for increased efforts in prevention.
