What is a Cellular Biology Degree?
Every living organism is made up of one or more cells. The cell is the fundamental unit of life. Cells are the structural and functional organization in organisms. All cells come from pre-existing cells that have multiplied. All biochemical processes are carried out by cells. These are the tenets of cell theory, proposed in 1837-1838. Cellular or cell biology is key to understanding how organisms develop, how they respond to their environment, and how the diseased state differs from the healthy state.
Diseases like meningitis, malaria, diabetes, cancer, cystic fibrosis, and Alzheimer’s are all caused by problems at a cellular or molecular level. By studying cells and understanding how they work, cell biologists are able to develop more effective medicines and new vaccines. But cell biology is not just about disease. It has applications in human fertility, genetic analysis and health forecasting, agriculture, sustainable fuels development, archaeology, and forensic science.
From single-celled bacteria to the trillions of cells that make up a human body, students of cell biology learn about cellular structure, composition, and regulation; cell growth; cellular division; and cell death.
- Degree programs in cellular biology may be offered as combined programs in molecular and cellular biology.
- Cellular biology is rarely offered as a major at the associate level. Related associate degrees in histology and histotechnology are much more common. These programs train students to work as specialized medical lab technicians, known as histotechnicians, who study tissue samples and prepare specimens for research or examination by pathologists. Core coursework includes histopathology laboratory theory, operations, and management; fundamental histotechnology techniques; and a histology practicum.

Graduate Certificate in Cellular Biology – Nine Month to Two Year Duration
The graduate certificate in cellular biology is aimed at graduate students in a variety of disciplines from agriculture to veterinary medicine, who are looking for professional training to add to their skill sets; working professionals seeking retraining and/or additional training; educators who require continue education credits; and non-degree seeking students who want interdisciplinary science and professional training. A bachelor’s degree in biology, biochemistry, cellular biology, chemistry, genetics, microbiology, or a related field is typically required for admission into the program.
These are examples of courses that may be part of the graduate certificate curriculum:

- Population Genetics – exploration of the patterns and dynamics of genetic variation in populations, and how they are connected to the processes that underlie evolution; topics include the quantification of genetic variation, mutation, selection and fitness, genetic drift, migration, population structure, quantitative traits, and adaptation at the molecular level; connecting genotype (genetic characteristics) with phenotype (physical characteristics) and ultimately with fitness; the evolution of drug resistance; experimental evolution of microbes
Doctoral Degree in Cellular Biology – Five to Six Year Duration
The goal of the Doctoral Degree in Cellular Biology is to prepare students for a future in research or academia, or for senior level non-academic career paths.
Sample areas of study / research:
Cell Structure and Function
- Cytoskeleton and cell motility (the spontaneous movement of a cell from one location to another by consumption of energy)
- Cell division and cell control
- Chromatin and gene expression

- Cellular metabolism
- Hormone action

Degrees Similar to Cellular Biology
The focus of biochemistry is the chemical processes and reactions that occur in living matter. Biochemists apply principles of both biology and chemistry to issues in many different sectors, including the environment, medicine and health, industry and manufacturing, agriculture, biofuels, and marine science.
A general biology degree program may include subjects like animal biology, invertebrate biology, vertebrate biology, cellular and molecular biology, evolution, microbiology, and ecology.
Simply stated, biomedical engineering uses engineering to solve health and medical problems. For example, a biomedical engineer might look for chemical signals in the body that warn of a particular disease or condition.
Majors in this field study engineering and the life sciences to create new products – such as vaccines, medicines, growth hormones for plants, and food additives – for the agricultural, industrial, and environmental industries. Among typical classes are biochemistry, general biology, cell biology, chemistry, and genetics.
Botany is the study of the physiology, structure, genetics, ecology, distribution, classification, and economic importance of plants. Degree programs in the field include courses in biochemistry, microbiology, photosynthesis, and plant evolution.
Cytotechnology is the study of cells and cellular anomalies. Cytotechnologists use a microscope to examine slides of human cells to uncover evidence of abnormalities that may reveal inflammation, infection, or disease.
Students who pursue a degree in ecology study how organisms interact with the natural environments that they live in and how these environments can be protected. In other words, the focus of ecology is to understand ecosystems as well as the social and political interests and policies that threaten them. An ecology curriculum, therefore, starts with courses in both the natural sciences – like biology, chemistry, physics, and geology – and the social sciences.
Genetics is concerned with how traits such as hair color, eye color, and risk for disease are passed or inherited from parents to their children, and how these inherited traits differ from person to person. At the center of the study of genetics is the genetic code or ‘genome.’ This genetic information is made up of a chemical called deoxyribonucleic acid (DNA) and is stored in almost every cell in the body.
In the broad sense, immunology is the field of biology which studies the immune system, also known as the body’s defense system. In medical terms, immunology is the subspecialty of internal medicine which deals with both the normal and abnormal functioning of the immune system.
Immunologists work with adult and pediatric patients suffering from common diseases such as asthma, food and drug allergies, immune deficiencies, and diseases of the lung. Their responsibilities in laboratory-based work involve conducting original medical research and experiments and developing new treatments, therapies, or vaccines to control infections and illnesses.
Microbiology is the study of all living organisms that are too small to see with the naked eye. These ‘microbes’ include bacteria, archaea, viruses, fungi, prions, protozoa, and algae.
The field of molecular biology is concerned with genetics, with the structure and the relationships between four molecules in the body: proteins, fats, carbohydrates, nucleic acids.
Pharmacologists study how drugs and medicines work so they can be used in the right way. The work naturally involves an understanding of chemical and biological interactions.
Zoology students learn about animals, their evolution, anatomy, physiology, and natural habitats. Graduates may be employed by zoos, veterinary clinics, or labs. Their work may involve monitoring and writing reports on animal behavior, analyzing specimens to test for diseases, and/or working in the areas of ecology and conservation.
