Background:

• Calculating cell population doubling time often requires complex manual computations.
• Accurate determination of cell doubling time is crucial for understanding tumor growth kinetics.

Purpose of the Study:

• To develop user-friendly computer software (DOUBLE-TIME) for automating and expediting the calculation of cell population doubling times.
• To provide a tool for analyzing both in vitro and in vivo tumor growth data.

Main Methods:

• Development of MS-DOS compatible software named DOUBLE-TIME.
• Database creation for cell number collection.
• Automated calculation of doubling time from cell growth plots.
• In vivo tumor volume calculation and growth curve generation.
• Software-based cell counting using a mouse interface.

Main Results:

• The DOUBLE-TIME software successfully automates cell counting and data collection.
• It accurately calculates doubling times for cell populations from growth curves.
• The software generates growth curves and determines mean doubling times for multiple tumors.
• It provides plotting of total and viable cell numbers and calculates the standard error of the doubling time.

Conclusions:

• The DOUBLE-TIME software significantly simplifies and accelerates the analysis of cell population doubling times.
• This tool enhances the efficiency of in vitro and in vivo tumor growth studies.
• Automated analysis improves accuracy and reduces the tedium associated with traditional calculation methods.
