Cancer research is the study of the biology, prevention, and treatment of cancer. Cancer is a complex and multifaceted disease that can arise from any tissue in the body and can affect individuals of all ages. According to the World Health Organization, cancer is the second leading cause of death globally, with an estimated 9.6…
Xenograft models have become an important tool in biomedical research, particularly in cancer research, allowing scientists to study the biology of human tumors in vivo. A xenograft model involves the transplantation of human tumor cells or tissue into an immunodeficient mouse, allowing the tumor to grow and be studied in a living organism. The history…
Xenograft models, also known as heterotransplantation models, are widely used in cancer research to study the biology of tumors and test the efficacy of new cancer therapies. In a xenograft model, human cancer cells or tissues are transplanted into an animal host, typically a mouse, to create a tumor that can be studied in vivo….
In vitro and in vivo studies are two fundamental approaches used in biological research to investigate the effects of various factors on living organisms. While both methods are critical for advancing our understanding of biological processes, they differ in important ways. In vitro studies, also known as “test-tube” studies, are conducted in a laboratory setting…
Non-clinical studies are those that are conducted outside of a healthcare setting, such as in a laboratory. They are an important part of the drug development process, providing information on how a new drug behaves in the body and how it is metabolized. Non-clinical studies are also important for safety testing. Benefits of non-clinical studies:…
A clinical study is a research study in which people volunteer to participate. The purpose of a clinical study is to answer specific questions about new therapies or new ways of using known treatments. Clinical studies are the main way that doctors find out if a new medical approach is safe and effective. The main…
Animals have been used in scientific research for centuries, with a wide range of species being used to study various aspects of biology, physiology, and disease. Animal research has played a critical role in advancing our understanding of the human body and in the development of new medical treatments. One of the primary reasons animals…
Cell lines are populations of cells that are cultured in vitro and have the ability to divide and grow indefinitely. They are an essential tool in many areas of research, including cancer biology, drug discovery, and tissue engineering. Cell lines are commonly used in experiments as they are a reliable and cost-effective alternative to using…
What is transfection? Transfection is the process of introducing foreign genetic material into eukaryotic cells. This can be done using a variety of techniques, including chemical or electrical means. Once the foreign DNA has been introduced, it can be expressed by the cell, resulting in the production of new proteins. Transfection is a powerful tool…
The laboratory mouse or lab mouse is a small mammal of the order Rodentia which is bred and used for scientific research or feeder for certain pets. Laboratory mice are usually of the species Mus musculus. They are the most commonly used mammalian research model and are used for research in genetics, physiology, psychology, medicine, and other scientific disciplines. Mice belong to the Euarchontoglires clade, which includes humans. This close relationship, the associated high homology with humans, their ease of maintenance…
