What are lab grown red blood cells?
Red blood cells (RBCs) that are produced in a laboratory rather than from human donors are referred to as lab-grown red blood cells, artificial red blood cells, or synthetic blood. Numerous medical applications, including as transfusions, regenerative medicine, and drug delivery systems, have a lot of potential in this field of study. Fully functional lab-grown red blood cells are still in the experimental stage and have not yet been widely used in clinical settings.
Red blood cells need to be cultivated in a specific environment that promotes their growth into red blood cells in order to be produced in a lab. These stem cells are often derived from bone marrow or induced pluripotent stem cells. The objective is to simulate erythropoiesis, the body's regular red blood cell production process.
Despite significant advancements, there are still a number of problems that need to be fixed in the lab-based manufacture of functional red blood cells. A few of these challenges include producing enough red blood cells, preserving their long-term viability and stability, and replicating the unique characteristics and qualities of natural red blood cells, such as their efficient capacity to carry and release oxygen.
It may not be long until lab-grown blood cells are used in blood transfusions. Since 2021, the National Health Service (NHS) of the United Kingdom has been working on the RESTORE initiative, which intends to create red blood cells from stem cells. In order to reduce the lifetime transfusion requirements for patients with blood diseases, the RESTORE project aims to develop an alternative blood transfusion therapy that is more effective than using donor blood.
Before lab-grown red blood cells are taken into consideration for clinical use, extensive safety and efficacy study would be required to ensure that they are both safe and effective in treating a variety of ailments. These evaluations would focus on the lifetime, immune system compatibility, and oxygen-delivery capacity of the synthetic red blood cells.
Blood is made up of a fluid called plasma and three primary cell types: platelets, white blood cells, and red blood cells. Red blood cells are produced in the bone marrow, which is found in the middle of most bones. Stem cells present in the bone marrow can be used to make red blood cells, white blood cells, and platelets.
The main job of red blood cells is to carry oxygen across the body. Red blood cells contain a protein called haemoglobin, which carries oxygen. Significant amounts of iron from our food are present in haemoglobin. Anaemia, which can result from low red blood cell counts, can also cause other issues like fatigue and dizziness. The most common type of anaemia, iron deficiency anaemia, can be treated with dietary adjustments and supplementation.
Sickle cell anaemia can also be caused by the condition. Patients with sickle cell anaemia have red blood cells that are C-shaped instead of the usual doughnut shape without a hole. Haemoglobin can't transfer oxygen as efficiently as a result. The cells also thicken and become very sticky, clumping and blocking blood vessels. Because sickle cells do not live as long as healthy red blood cells do, the body does not have enough red blood cells.
It's important to remember that scientific breakthroughs happen quickly, and there might have been other developments in this area. Therefore, to get the most recent information about lab-grown red blood cells, it's always a good idea to check the most recent scientific literature or get in touch with pertinent experts.
