Abstract

A method for assisting in cell isolation from a biological tissue section includes: obtaining cell images that are each an image of cells isolated from the biological tissue section, the biological tissue section being soaked in a solution containing an enzyme; calculating, from the cell images, a number of the cells isolated from the biological tissue section as an indicator of the cell isolation from the biological tissue section; and visualizing a temporal change in the indicator on the basis of a history of the indicator.

Claims (67)

1. A method for assisting in cell isolation from a biological tissue section, the method comprising:

obtaining cell images that each include an image containing cells isolated from the biological tissue section, the biological tissue section being soaked in a solution containing an enzyme, and the cell images being images obtained during an isolation process when cells are being isolated from the biological tissue section;

calculating, from the cell images, a number of the cells isolated from the biological tissue section as an indicator of the cell isolation from the biological tissue section; and

visualizing a temporal change in the indicator on the basis of a history of the indicator.

2. The method according to claim 1 , wherein the obtained cell images that further include the image containing at least a portion of the biological tissue section.

3. A method for assisting in cell isolation from a biological tissue section, the method comprising:

obtaining cell images that each include an image containing cells isolated from the biological tissue section, the biological tissue section being soaked in a solution containing an enzyme, and the cell images being images obtained during an isolation process when cells are being isolated from the biological tissue section;

calculating, from the cell images, a contrast of the cell images as an indicator of the cell isolation from the biological tissue section; and

visualizing a temporal change in the indicator on the basis of a history of the indicator.

4. The method of claim 3 , further comprising:

calculating, from the cell images, a number of the cells isolated from the biological tissue section as an indicator of the cell isolation from the biological tissue section.

5. The method of claim 3 , wherein

the visualizing the temporal change in the indicator includes displaying a graph indicating the temporal change in the indicator.

6. The method of claim 5 , further comprising:

displaying an image captured at a most recent imaging time point among the cell images.

7. The method of claim 5 , further comprising:

displaying, among the cell images, an image that corresponds to an imaging time indicated by a selected position on the graph.

8. The method of claim 3 , further comprising:

determining a progress status of the cell isolation on the basis of a temporal change in the indicator; and

reporting the progress status of the cell isolation on the basis of a result of the determination of the progress status of the cell isolation.

9. The method of claim 8 , wherein

the determining the progress status of the cell isolation includes determining whether the cell isolation has been completed on the basis of the temporal change in the indicator, and

the reporting the progress status of the cell isolation includes reporting completion of the cell isolation on the basis of the result of the determination of the progress status of the cell isolation.

10. The method of claim 9 , wherein

the determining whether the cell isolation has been completed includes

determining whether the temporal change in the indicator has converged, and

determining that the cell isolation has been completed when it is determined that the temporal change in the indicator has converged.

11. The method of claim 8 , wherein

the reporting the progress status of the cell isolation on the basis of the result of the determination of the progress status of the cell isolation is performed through wireless communication with a terminal.

12. The method of claim 8 , wherein

the reporting the progress status of the cell isolation includes visually displaying an image or text indicating the progress status of the cell isolation.

13. The method of claim 3 , further comprising:

estimating a time required to complete the cell isolation by using a database or a learning-completed model, and displaying the estimated time.

14. The method according to claim 3 , wherein

the cell images include a plurality of cell images obtained at different times in the isolation process, and

the indicator is calculated from each of the plurality of cell images.

15. The method according to claim 3 , wherein the cell images include an image obtained by imaging the biological tissue section soaked in the solution containing an enzyme.

16. The method according to claim 3 , wherein the obtained cell images that further include the image containing at least a portion of the biological tissue section.

17. A system comprising:

an image capturing apparatus configured to image cells isolated from a biological tissue section soaked in a solution containing an enzyme; and

a control apparatus configured to obtain, from the image capturing apparatus, cell images that each include an image containing the cells isolated from the biological tissue section, and the cell images being images obtained during an isolation process when cells are being isolated from the biological tissue section,

wherein the control apparatus is configured to:

calculate, from the obtained cell images, a number of the cells isolated from the biological tissue section as an indicator of the cell isolation from the biological tissue section, and

visualize a temporal change in the calculated indicator on the basis of a history of the indicator.

18. The system of claim 17 , wherein

the control apparatus is configured to

calculate, from the obtained cell images, a contrast of the cell images as an indicator of the cell isolation from the biological tissue section.

19. The system according to claim 17 , wherein the obtained cell images that further include the image containing at least a portion of the biological tissue section.

20. A system comprising:

an image capturing apparatus configured to image cells isolated from a biological tissue section soaked in a solution containing an enzyme; and

a control apparatus configured to obtain, from the image capturing apparatus, cell images that each include an image containing the cells isolated from the biological tissue section, and the cell images being images obtained during an isolation process when cells are being isolated from the biological tissue section,

wherein the control apparatus is configured to:

calculate, from the obtained cell images, a contrast of the cell images as an indicator of cell isolation from the biological tissue section, and

visualize a temporal change in the calculated indicator on the basis of a history of the indicator.

21. The system according to claim 20 , wherein the obtained cell images that further include the image containing at least a portion of the biological tissue section.

22. A non-transitory computer-readable medium having recorded therein a program for causing a computer to perform a process for:

obtaining cell images that each include an image containing cells isolated from a biological tissue section soaked in a solution containing an enzyme, and the cell images being images obtained during an isolation process when cells are being isolated from the biological tissue section;

calculating, from the obtained cell images, a number of the cells isolated from the biological tissue section as an indicator of cell isolation from the biological tissue section; and

visualizing a temporal change in the calculated indicator on the basis of a history of the indicator.
