Week 1 Tissue and Cell Culture Techniques
Tissue and Cell Culture Techniques: Introduction
Here are the key points from the lecture on tissue and cell culture techniques, with a focus on
cancer:
### Key Points
1. **Understanding Cancer**:
- Cancer involves uncontrolled cell division, leading to abnormal cell accumulation in the body.
2. **Cell Culture Techniques**:
- **In-vivo**: Studies conducted within a living organism.
- **Ex-vivo**: Studies performed on tissues or cells taken from an organism and maintained in
an artificial environment.
- **In-vitro**: Experiments done in a controlled environment outside of a living organism, such
as in a laboratory.
3. **Importance of Cell and Tissue Culture**:
- Combines biology, medicine, and engineering.
- Essential for understanding cancer progression and developing electronic systems for
diagnosis and treatment.
4. **Cell Structure**:
- Cells consist of various organelles (nucleus, ribosomes, mitochondria, etc.) with complex
structures and functions.
- The nucleus can be stained (e.g., with DAPI) to distinguish cells from debris.
5. **Cell Theory**:
- Formulated by scientists like Robert Hooke and Rudolf Virchow.
- States that all living organisms are composed of cells, and cells arise from pre-existing cells.
6. **Conductivity and Drug Efficacy**:
- Cell lysis releases conductive materials, increasing conductivity.
- This property can be used to develop sensors for drug efficacy, allowing for drug screening.
7. **Nanoparticle Drug Delivery**:
- Nanoparticles can enhance drug retention within cells by mimicking cell membrane
components, reducing efflux and prolonging the drug's effect.
8. **Blood-Brain Barrier**:
, - A significant challenge in drug delivery to the brain.
- Nanoparticles can be engineered to cross this barrier effectively.
9. **Stem Cells and Drug Delivery**:
- Neural stem cells could serve as a novel mechanism for drug delivery in brain cancer
treatment.
10. **Next Steps**:
- The upcoming module will focus on cell culture techniques and the equipment required for
effective cell culture.
### Conclusion
Understanding cell culture techniques is crucial for developing diagnostic and therapeutic
strategies for cancer. The integration of biology, medicine, and engineering plays a vital role in
advancing cancer research and treatment technologies.
Tissue and Cell Culture Techniques: Methods
### Key Points on Cell Culture Techniques
1. **Definitions:**
- **Cell Culture:** The process of cultivating cells and tissues outside an organism's body in
an artificial environment (ex-vivo).
- **In-Vivo:** Studying cells within the body.
- **In-Vitro:** Studying cells in an artificial environment like a petri dish.
2. **Historical Context:**
- First successful cell culture by Ross Harrison in 1907.
3. **Types of Cell Culture:**
- **Primary Cell Culture:** Cells surgically removed from an organ and placed in a suitable
environment to grow.
- **Cell Line:** When primary cells are sub-cultured and can propagate indefinitely.
- **Adherent Cells:** Cells that grow as a monolayer, adhering to surfaces like glass or plastic.
4. **Culture Process:**
- Isolation of tissue followed by disaggregation (mechanical or enzymatic).
- Cells are cultured until they reach confluence (approx. 80% coverage).
- **Sub-Culturing:** Splitting of confluent cultures into new flasks for continued growth.
5. **Disaggregation Techniques:**
, - **Mechanical:** Using tools like pestles or mortars.
- **Enzymatic:** Using trypsin or collagenase to break down tissues.
6. **Incubator Conditions:**
- Maintain 37°C, 5% CO2, and 95% relative humidity to mimic in-vivo conditions.
7. **Cryopreservation:**
- Process to preserve cells for long-term storage by freezing at -80°C and later transferring to
liquid nitrogen.
8. **Applications:**
- Understanding drug efficacy for cancer treatment through patient-centric drug screening
platforms.
9. **Terminology Recap:**
- **Confluence:** Estimate of the proportion of surface covered by cells.
- **Passaging:** The process of splitting cells for sub-culture.
10. **Next Steps:**
- Upcoming discussions on the advantages, limitations, and applications of tissue culture,
along with a lab setup overview.
### Note:
Balance studies with physical activities and mental well-being!

- Interdisciplinary collaboration between engineers and scientists in bioengineering.
### Cell Theory and Culture
- **Cell Theory**: Foundation of understanding cells.
- **Cell Culture Types**:
- **In vivo**: Within a living organism.
- **Ex vivo**: Outside a living organism but in a biological context.
- **In vitro**: In a controlled laboratory environment.
### Cell Culture Concepts
