Title: Molecular Profiles of Cell-to-Cell Variation in the Regenerative Potential of Mesenchymal Stromal Cells
Cell-to-cell variation in the regenerative potential of mesenchymal stromal cells (MSCs) impedes the translation of MSC therapies into clinical practice. Cellular heterogeneity is ubiquitous across MSC cultures from different species and tissues. This review highlights advances to elucidate molecular profiles that identify cell subsets with specific regenerative properties in heterogeneous MSC cultures. Cell surface markers and global signatures are presented for proliferation and differentiation potential, as well as immunomodulation and trophic properties. Key knowledge gaps are discussed as potential areas of future research. Molecular profiles of MSC heterogeneity have the potential to enable unprecedented control over the regenerative potential of MSC therapies through the discovery of new molecular targets and as quality attributes to develop robust and reproducible biomanufacturing processes. These advances would have a positive impact on the nascent field of MSC therapeutics by accelerating the development of therapies with more consistent and effective treatment outcomes.  more » « less

    Abstract In vivo mesenchymal stem cell (MSC) survival is relevant to therapeutic applications requiring engraftment and potentially to nonengraftment applications as well. MSCs are a mixture of progenitors at different stages of cellular aging, but the contribution of this heterogeneity to the survival of MSC implants is unknown. Here, we employ a biomarker of cellular aging, the decoy TRAIL receptor CD264, to compare the survival kinetics of two cell populations in human bone marrow MSC (hBM‐MSC) cultures. Sorted CD264+hBM‐MSCs from two age‐matched donors have elevated β‐galactosidase activity, decreased differentiation potential and form in vitro colonies inefficiently relative to CD264−hBM‐MSCs. Counterintuitive to their aging phenotype, CD264+hBM‐MSCs exhibited comparable survival to matched CD264−hBM‐MSCs from the same culture during in vitro colony formation and in vivo when implanted ectopically in immunodeficient NIH III mice. In vitro and in vivo survival of these two cell populations were independent of colony‐forming efficiency. These findings have ramifications for the preparation of hBM‐MSC therapies given the prevalence of aging CD264+cells in hBM‐MSC cultures and the popularity of colony‐forming efficiency as a quality control metric in preclinical and clinical studies with MSCs.

    Combination of stem cell technology and 3D biofabrication approaches provides physiological similarity to in vivo tissues and the capability of repairing and regenerating damaged human tissues. Mesenchymal stem cells (MSCs) have been widely used for regenerative medicine applications because of their immunosuppressive properties and multipotent potentials. To obtain large amount of high-quality MSCs without patient donation and invasive procedures, we differentiated MSCs from human-induced pluripotent stem cells (hiPSC-MSCs) using serum-free E6 media supplemented with only one growth factor (bFGF) and two small molecules (SB431542 and CHIR99021). The differentiated cells showed a high expression of common MSC-specific surface markers (CD90, CD73, CD105, CD106, CD146, and CD166) and a high potency for osteogenic and chondrogenic differentiation. With these cells, we have been able to manufacture MSC tissue rings with high consistency and robustness in pluronic-coated reusable PDMS devices. The MSC tissue rings were characterized based on inner diameter and outer ring diameter and observed cell-type-dependent tissue contraction induced by cell-matrix interaction. Our approach of simplified hiPSC-MSC differentiation, modular fabrication procedure, and serum-free culture conditions has a great potential for scalable manufacturing of MSC tissue rings for different regenerative medicine applications.

    Abstract Recent developments in mesenchymal stromal cell (MSC) therapies have increased the demand for tools to improve their manufacture, including the selection of optimal culture substrate materials. While many clinical manufacturers use planar tissue culture plastic (TCP) surfaces for MSC production, others have begun exploring the use of alternative culture substrates that present a variety of spatial, mechanical, and biochemical cues that influence cell expansion and resulting cell quality. In this review, the effects of culture and material properties distinct from traditional planar TCP surfaces on MSC proliferation, surface marker expression, and commonly used indications for therapeutic potency are examined. The different properties summarized include the use of alternative culture formats such as cellular aggregates or 3D scaffolds, as well as the effects of culture substrate stiffness and presentation of specific adhesive ligands and topographical cues. Specific substrate properties can be related to greater cell expansion and improvement in specific therapeutic functionalities, demonstrating the utility of culture materials in further improving the clinical‐scale manufacture of highly secretory MSC products.

    Abstract BackgroundWhile mesenchymal stromal cell (MSC) therapies show promise for treating several indications due to their regenerative and immunomodulatory capacity, clinical translation has yet to be achieved due to a lack of robust, scalable manufacturing practices. Expansion using undefined fetal bovine serum (FBS) or human platelet lysate contributes to MSC functional heterogeneity and limits control of product quality. The need for tunable and consistent media has thus motivated development of chemically defined media (CDM). However, CDM development strategies are often limited in their screening approaches and unable to reliably assess the impact of media on MSC function, often neglecting high-level interactions of media components such as growth factors. Given that MSC morphology has been shown to predict their immunomodulatory function, we employed a high throughput screening (HTS) approach to elucidate effects of growth factor compositions on MSC phenotype and proliferation in a custom CDM. MethodsHTS of eight growth factors in a chemically defined basal medium (CDBM) was conducted via a two-level, full factorial design using adipose-derived MSCs. Media hits were identified leveraging cell counts and morphological profiles. After validating phenotypic responses to hits across multiple donors, MSCs were cultured over three passages in serum-containing medium (SCM) and CDM hits and assayed for growth and immunomodulatory function. Finally, growth factor concentrations in one hit were further refined, and MSC growth and function was assessed. ResultsOur HTS approach led to the discovery of several CDM formulations that enhanced MSC proliferation and demonstrated wide ranging impacts on MSC immunomodulation. Notably, two hits showed 4X higher growth compared to SCM over 3 passages without compromising immunomodulatory function. Refinement of one CDM hit formulation reduced growth factor concentrations by as much as 90% while maintaining superior growth and similar function to SCM. Altogether, distinct MSC morphological profiles observed from screening were indicative of differential MSC quality that allowed for development of an effective CDM for MSC expansion. ConclusionsOverall, this highlights how our HTS approach led to the development of CDM formulations for robust MSC expansion and serves as a generalizable tool for improvement of MSC manufacturing processes.
