Methods to Assess Microbial Populations01:30

Methods to Assess Microbial Populations

Assessing microbial populations is crucial for understanding microbial roles in health, ecology, and industry. Various complementary techniques—both culture-based and molecular—enable detailed analysis of microbial abundance, diversity, and function.Viable Plate CountThe viable plate count is a traditional culture-based method used to estimate the number of living microbes in a sample. After serial dilution, the sample is spread onto nutrient agar plates. Each viable cell forms a visible...

  • Biomedical Engineering
  • Cell Biology
  • Regenerative Medicine

Background:

  • Mesenchymal stem cells (MSCs) are vital for tissue engineering and transplantation therapies.
  • Controlling MSC differentiation is critical for stem cell therapy efficacy and safety, as heterogeneity can cause tumorigenic issues.

Purpose of the Study:

  • To develop an automated model for evaluating the differentiation status of mesenchymal stem cells (MSCs).
  • To address the heterogeneity of MSCs differentiating into adipogenic or osteogenic lineages using label-free imaging techniques.

Main Methods:

  • Acquisition of label-free microscopic images using fluorescence lifetime imaging microscopy (FLIM) and stimulated Raman scattering (SRS).
  • Development of an automated evaluation model based on the K-means machine learning algorithm to analyze cell differentiation status.

Main Results:

  • The developed model demonstrated highly sensitive analysis of individual cell differentiation status.
  • The model effectively addresses MSC heterogeneity during differentiation into adipogenic and osteogenic lineages.

Conclusions:

  • The automated K-means model shows significant potential for advancing stem cell differentiation research.
  • This label-free imaging and machine learning approach offers precise control over MSC differentiation for improved tissue engineering and clinical applications.
