Background:

Standard methods for animal tissue cell dispersion often face challenges with efficiency and cell viability.
Existing techniques may require lengthy processing times and result in significant cell clumping.
Optimizing cell dispersion is crucial for downstream applications in research and therapeutics.

Purpose of the Study:

To describe a novel technique for enhanced dispersion of animal tissue cells.
To evaluate the efficacy of combining trypsin with disodium ethylenediamine tetraacetate (EDTA) for cell dispersal.
To compare the proposed method against standard cell dispersion techniques.

Main Methods:

A new cell dispersion protocol was developed utilizing the combined action of trypsin and disodium ethylenediamine tetraacetate (EDTA).
Animal tissue samples were processed using the novel technique.
The outcomes were quantitatively and qualitatively assessed against conventional trypsinization methods, focusing on cell yield, time, viability, clumping, and monolayer formation.

Main Results:

The concomitant use of trypsin and disodium EDTA markedly enhanced overall cell yield.
Significant reductions in the time required for complete tissue dispersal were observed.
The technique resulted in a very low number of nonviable cells, reduced cell clumping, and more uniform monolayer formation during cultivation.

Conclusions:

The combined use of trypsin and disodium EDTA offers a superior method for animal tissue cell dispersion.
This enhanced technique provides significant advantages in terms of efficiency, cell viability, and culture quality over standard methods.
The improved cell dispersion has broad implications for various biological research and biotechnological applications.
