Metabolomics in Regenerative Medicine

Metabolomics comprehensively characterizes small polar and lipid metabolites, yielding a snapshot of cellular processes and biochemical reactions that are dependent on the physiological (or pathological) state of cells, tissues, and organs. Therefore, metabolomics is a valuable tool for the understanding of stem cell fate, physiology, and mechanisms in the context of regenerative medicine and stem cell bioprocessing. Moreover, metabolomics can be applied to study the distinctions in the metabolic profile of different classes of stem cells, including the development stages i.e., proliferation, differentiation, etc. These applications can provide insights on disease mechanisms and novel biological pathways, thus, helping to unleash the full translational potential of stem cells.

Metabolomics brings us closer to the phenotype of an individual, providing a direct readout of metabolic changes that regulate stem cell function.


HMT’s metabolomics

HMT’s metabolome analysis employs CE-MS & LC-MS platforms. Our technologies are optimized to capture signaling metabolites, polyamines, energy metabolism in many types of samples, including blood, tissues, organoids and cultured cells.

Quantitation Quantitation
Over 100 polar metabolites, many of which are involved in cell regeneration are quantifiable with single- or multi-point calibration.
High resolution High resolution
Good separation of structural isomers, e.g. isobaric fatty acids, oxidative products.

Examples of samples that can be analyzed at HMT

Cultured cells

  • distinguish metabolite profiles of different classes of stem cells
  • understand the regulatory mechanisms that control differentiation, etc.
Culture medium, supernatant

  • optimize culture conditions
  • examine metabolic changes associated with cell proliferation & differentiation
Serum, plasma, biofluids

  • evaluate the detectability and fluctuations of metabolite markers
  • discover biomarkers associated with toxins and rejection of tissue grafts
Organoid

  • monitor the quality of organoid differentiation & maturation
  • identify time-dependent metabolic changes in organoids
Tissues from target organs

  • assess current therapies, e.g. organogenesis during bone marrow transplantation
  • compare metabolic profiles pre- and post-differentiation
