1. Biotechnology

Biotechnology is the exploitation and application of biological organisms and/or processes for industrial and other purposes. Biotechnology primarily involves the genetic manipulation of microorganisms for the production of specific products.

To put it in a simple way, Biotechnology is the use of living systems and organisms to develop or make products, or “any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use”. The ultimate objective of biotechnology is to improve the quality of human life and health.

Under the broad field of biomedical sciences, the three important verticals (or sub-domains) are Regenerative Medicine & Stem Cells, Translational Medicine, and Diagnostics. However, please be advised that it’s only wise to go for the following three specializations only at the postgraduate level. However, it would be advantageous to get exposure at the Bachelors level through projects, internships, and online courses.

Regenerative Medicine and Stem Cells

Regenerative medicine (RM) is one of the most recent and trending branches of translational medicine. In terms of knowledge-base & practicalities, regenerative medicine revolves around tissue engineering (a specific niche within biomedical engineering), molecular & cell biology, immunology and stem cell biology.

Its main objective is to replace, repair (or modify), or regenerate human cells, tissues or organs for re-establishing or restoring normal condition from a pathologic/diseased condition (severe injury or chronic disease). RM leverages body’s own repair mechanisms to functionally heal irreparable tissues or organs.

The traditional medicine & therapeutics basically treat the symptoms of a disease. In contrast, regenerative medicine aims to treat the underlying cause of a disease. Traditional pharmacological approaches have been incredibly successful in treating various acute and chronic diseases and disorders. With time, those discoveries also enhanced our understanding of the underlying mechanisms of diseases and consequently led to innovative therapies that focus on addressing the causes of the disease instead of just treating symptoms. But, millions of patients still suffer from diseases for which there is no treatment at all.

Stem Cells

Stem cells, which are found in multicellular organisms (organs, tissues, blood, immune system), have got the unique ability to develop into various cell types in the body during early life and growth. Additionally, stem cells also serve as a sort of internal repair system in many tissues, dividing essentially indefinitely(yes, without any limit) to replenish other cells as long as the organism (human or animal) is still alive. On dividing, each new stem cell can become a stem cell or another type of cell with a more specialized function, e.g. a red blood cell, a nerve cell, a muscle cell, a cardiomyocyte (heart muscle cell) or a brain cell.

Translational Medicine

Within the broad field of biomedical science, Translational Medicine (or Translational Research) is also gaining a lot of popularity. It is a very new field, still emerging, and holds the future for advancements in the field of human medicine. Translational Medicine is the fundamental science to develop new diagnostic tools and treatments, and similarly using the research findings from the clinic (clinical trials) to develop new research ideas for basic science.

Diagnostics involve tests/procedures ordered by a physician and office visits needed to help diagnose or monitor a clinical condition or disease. Diagnostic care is basically a follow up of an issue from an irregular test result, an existing illness, injury or health problem already being treated by your doctor like diabetes, COPD, allergies, and more. The field of diagnostics can be classified into two major categories – in vivo diagnostics and in vitro diagnostics.

The in vivo segment (can also be termed as the Radiology segment) includes the medical imaging procedures such as magnetic resonance imaging (MRI), ultrasound scanning, sonography, X-Ray, mammography, positron emission tomography (PET), colonoscopy, Computer Axial Tomography (CT scan) etc. The in vivo tests (can also be termed as the Pathology segment) are performed directly on a human body (patient).

Top Career Paths in Life and Biological Sciences - Diagnostics

The in vitro diagnostic tests involve processing and investigation of biological samples, collected directly from the patient, such as blood, urine, saliva, tissues, faces etc. The human samples are analyzed in a laboratory setting to detect and quantify the presence of a specific biological marker (biomarker). A biomarker could be a circulating protein, pathogen, electrolyte and even genetic mutation.
