BACKGROUND: Kidney diseases are a global health problem. Currently, over 2
million people require dialysis or transplant which are associated with high
morbidity and mortality; therefore, new researches focused on regenerative
medicine have been developed, including the use of stem cells. RESULTS: In this
research, we generate differentiated kidney cells (DKCs) from mouse pluripotent
stem cells (mPSCs) analyzing their morphological, genetic, phenotypic, and
spectroscopic characteristics along differentiation, highlighting that there are
no reports of the use of Fourier transform infrared (FTIR) spectroscopy to
characterize the directed differentiation of mPSCs to DKCs. The genetic and
protein experiments proved the obtention of DKCs that passed through the
chronological stages of embryonic kidney development. Regarding vibrational
spectroscopy analysis by FTIR, bands related with biomolecules were shown on
mPSCs and DKCs spectra, observing distinct differences between cell lineages and
maturation stages. The second derivative of DKCs spectra showed changes in the
protein bands compared to mPSCs. Finally, the principal components analysis
obtained from FTIR spectra allowed to characterize chemical and structurally
mPSCs and their differentiation process to DKCs in a rapid and non-invasive way.
CONCLUSION: Our results indicated that we obtained DKCs from mPSCs, which passed
through the chronological stages of embryonic kidney development. Moreover, FTIR
spectroscopy resulted in a non-invasive, rapid and precise technic that together
with principal component analysis allows to characterize chemical and
structurally both kind of cells and also discriminate and determine different
stages along the cell differentiation process.
