Phenomics - Coding x High-Throughput Imaging (2D/3D Models)
My portfolio on high-throughput imaging of 2D and 3D cell cultures and image analysis. :)

Introduction
As a proud member of the Siriraj Center of Research Excellence for Systems Pharmacology (SiSP), a leader in high-throughput imaging, I am driven by a passion for uncovering the secrets of cancer biology. My work combines a hands-on approach in the lab with cutting-edge image analysis. I have specialized in exploring a wide array of cellular models, moving from the traditional 2-dimensional (2D) cell cultures to advanced 3-dimensional (3D) multicellular spheroids and multi-spheroid systems. This diverse experience allows me to tackle complex biological questions with creativity and precision. Beyond the visuals, I am also an expert in using RStudio to dive deep into the data, ensuring that every image tells a complete and compelling story.
Model 1: 2D Cancer Cell Culturing Model
1.1 Analysis overview:
In this model, my work centered on utilizing cancer stem cell (CSC) reporter systems (SORE6 reporter) to study the dynamics of cancer cells in a flat, 2D environment. I employed high-content real-time imaging to precisely monitor the CSC phenotype and understand its behavior over time.
A key part of this work involved a high-throughput drug response study, where I evaluated the effects of various drugs on cancer cells, with a specific focus on their impact on the CSC population. Using this approach, I was able to establish a direct link between CSC biology and drug response. By analyzing the data, I could determine how much a specific drug concentration killed the cells, and in parallel, how that same concentration affected the percentage of cancer stem cells.
I also developed a detailed step-by-step methodology to create an algorithm that could compare the effects of different drugs on the CSC proportion across a comparable dose range. This systematic approach allowed for a robust comparison of drug efficacies from the perspective of both general cell death and the specific targeting of the CSC population. The imaging data was then analyzed using Columbus™ Image Data Storage and Analysis System (PerkinElmer), enabling a sophisticated, single-cell level analysis. The resulting data was further explored and visualized using RStudio, revealing a comprehensive view of drug efficacy and its influence on CSCs.
1.2 Key Applications:
- Monitoring CSC Phenotype: Used a reporter system with high-content real-time imaging to precisely monitor the behavior of cancer stem cells (CSCs).

-
High-Throughput Drug Screening: Performed drug response studies to evaluate the effects of various drugs on cancer cells, with a specific focus on their impact on the CSC population.
-
Linking CSC Biology and Drug Response: Established a direct link between a drug’s concentration, its cytotoxic effect, and its parallel impact on the percentage of CSCs.

- Algorithmic Drug Comparison: Developed a detailed methodology to create an algorithm for comparing how different drugs affect the CSC proportion across a comparable dose range.

1.3 Methods and Tools:
-
Wet Lab: Cultured CSC reporter-containing cell lines for phenotypic observation and drug response studies.
-
Imaging: Performed high-content and high-throughput imaging, including real-time, live-cell, and fixed-cell techniques.
-
Image Analysis: Conducted single-cell level analysis using Columbus™ software (PerkinElmer).
-
Data Analysis: Utilized RStudio for further data exploration, visualization, and statistical analysis.
Model 2: 3D Cancer Cell Culturing Model (3D Multicellular Spheroid, 3D Multi-Spheroid)
2.1 Analysis overview:
To create a more realistic and complex environment for cancer studies, I developed and investigated advanced 3D culturing models, including both 3D multicellular spheroids and multi-spheroid systems. This approach allowed me to move beyond the limitations of 2D culture and study CSC phenotypes within a more natural, three-dimensional context using high-content imaging.
I also conducted tumorigenic assays, which are crucial for understanding the potential of cancer cells to form tumors. This was done with high-throughput imaging and subsequent image analysis at the single spheroid level using PerkinElmer’s Columbus software. This detailed analysis provided valuable insights into the growth and behavior of tumors in a 3D setting. The data was then rigorously analyzed using RStudio to draw meaningful conclusions about the tumorigenic potential of the cells.
2.2 Key Applications:
- Investigating CSC Phenotype in 3D: Used high-content and high-throughput imaging to study CSC phenotypes in a more realistic 3D context, including multicellular spheroids and multi-spheroid systems.

- Tumorigenic Assays: Performed high-throughput imaging-based tumorigenic assays to understand the potential of cancer cells to form tumors.

- Linking CSC Biology and Drug Response: Established a direct link between a drug’s concentration, its cytotoxic effect, and its parallel impact on the content of CSCs in the 3D contexts, including multicellular spheroids and multi-spheroid systems.

2.3 Methods and Tools:
-
Wet Lab: Created and cultured 3D multicellular spheroids and multi-spheroid systems.
-
Imaging: Performed high-content and high-throughput confocal imaging on live and fixed cells.
-
Image Analysis: Conducted single-spheroid level analysis using Columbus™ software (PerkinElmer).
-
Data Analysis: Utilized RStudio for rigorous analysis to draw meaningful conclusions about tumorigenic potential.
1.3 What I’ve Learned
There are many ways to approach imaging data, often guided by applications from instrument companies or published studies. However, at its core, we’re really dealing with biology. In my case, it’s the biology of CSCs. I needed to understand the gaps in the CSC field and how I could use available applications to fill them.
I noticed that when studying CSC-mediated drug resistance, researchers often use a single drug concentration to show CSC enrichment or depletion. Yet, in a real tumor, the drug exists in a range of concentrations, not just one. To address this, I created an experiment to analyze the dose-response relationship alongside the CSC content. I was also curious about how different drugs affect CSC content.
Without coding, this kind of single-cell (in 2D) or spheroid (in 3D) analysis would be impossible. Coding speeds up the analysis and enables powerful data visualization. This doesn’t just create beautiful figures; it also provides meaningful insights for exploratory data analysis (EDA).

Last note from me
- I’m sorry for coding resource. I will upload the R code to my GitHub as soon as possible. The code is very unreadable (even to me, haha 😆😆!), because these image analysis scripts were some of my very first coding projects. I was practicing by doing real-world data analysis (Yes!, my Ph.D. thesis), and looking back at it now, it feels like I’m recalling a previous life. That’s because of my poor coding practices at the beginning (when I didn’t have any support from an LLM at that time).
- Another publication which directly relates to this “Phenomics- Coding x High-Throughput Imaging (2D/3D Culturing Models)” is under review. Once it is published I will update this page with more information. Please bear with me!🤗
I’m very happy 🥰 that you are visiting my computational biology portfolio and would be even happier if you could provide suggestions or feedback 🤩.
