🔴a short time with stem knowledge(1)

part 1:
Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.
Stem cells are distinguished from other cell types by two important characteristics. First, they are unspecialized cells capable of renewing themselves through cell division, sometimes after long periods of inactivity.

📎part 2:
Second, under certain physiologic or experimental conditions, they can be induced to become tissue- or organ-specific cells with special functions.
In some organs, such as the gut and bone marrow, stem cells regularly divide to repair and replace worn out or damaged tissues. In other organs, however, such as the pancreas and the heart, stem cells only divide under special conditions...

خودنوزایی یا self renewal : خودنوزایی که از ویژگی های مهم سلول های بنیادی است، به این معنیست که سلول بنیادی قادر است خود را برای مدت طولانی بازتولید کند؛ یعنی این سلول ها توانایی تکثیر و تقسیم مداوم داشته و از این نظر محدودیتی ندارند.
در برخی از اندامها، مانند روده و مغز استخوان، سلول های بنیادی به طور مرتب برای اصلاح و جایگزینی بافت‌های فرسوده یا آسیب دیده تقسیم می‌شوند اما در سایر اندام‌ها، مانند پانکراس و قلب، سلول های بنیادی فقط تحت شرایطی خاص تقسیم می‌شوند...

🔴A short time with stem knowledge(3)

▫️totipotent stem cells:
Part1:

You may already be familiar with the basics of stem cells but perhaps you weren't aware that there are different types, or potencies of stem cells.
Totipotent stem cells are one of the most important stem cells types because they have the potential to develop into any cell found in the human body. In human development, the egg cell in a woman and the sperm cell from a man fuse together to form a single cell called the zygote. The zygote divides numerous times and forms cells that are the precursors to the trillions of cells that will eventually constitute the human body...

📎part2:

It may sound rather complex and in a sense it is, when you consider that a simple cell has the potential to develop into a specialised one with a specific job in the body. It is simple, however, in that it's a clear sequence of events that begins with an egg cell and a sperm cell. The zygote from that fusion of an egg cell and a sperm cell then begins cell divisions that are capable of forming the entire human body. It is these cells that are totipotent, so called because their potential is 'total.'

▫️pluripotent stem cells:
Part 1:
Pluripotent stem cells are often termed 'true' stem cells because they have the potential to differentiate into almost any cell in the body. This means that under the right circumstances, a stem cell that is isolated from an embryo can produce almost all of the cells in the body. Yet after this embryonic development stage is over, the stem cells no longer have this unlimited potential to develop into all cell types. Their pluripotency is thus lost and they can only become certain types of cells.
To understand how a cell becomes pluripotent, it helps to consider the human body in the very early stages of development. After an egg is fertilised by a sperm, a single cell results. This cell - the fertilised egg that is totipotent - has the potential to create an entire organism...

#a_short_time_with_stem_knowledge 📝

@kums_stemcell

📎Part 2:

... In the initial hours and days following fertilisation, this single totipotent cell divides into more totipotent cells that are exact copies of the original.
Approximately four days after fertilisation, the totipotent cells start to specialise and form a cluster of cells known as a blastocyst. The blastocyst has yet another smaller group of cells known as the inner cell mass and it is these inner pluripotent stem cells that will go on to create most of the cells and tissues in the human body. These pluripotent stem cells are therefore different than totipotent stem cells because they don't develop into a complete organism. As such, a pluripotent cell won't give rise to the placenta or other tissues that are vital for foetal development. It will still develop into the other specialised cell types in the human body, such as nerve or heart cells.

▫️Multipotent Stem Cells:
Multipotent stem cells have the same basic features of all stem cells. As with all stem cells multipotent stem cells are unspecialized cells that have the ability to: Self-renew for long periods of time and differentiate into specialized cells with specific functions
A multipotent stem cell can give rise to other types of cells but it is limited in its ability to differentiate. These other types of cells are also limited in numbers. Examples of multipotent stem cells include those in the brain that give rise to different neural cells and glia or haematopoietic cells, which can give rise to different blood cell types, but they can't create brain cells. Bone marrow also contains multipotent stem cells that give rise to all blood cell types but not other cells.
Hence, adult stem cells are considered multipotent because their specialization potential is limited to one or more cell lines.

@kums_stemcell

📎Part2:

...However, a multipotent stem cell known as a mesenchymal stem cell can give rise to several cell types. This particular stem cell has been found to give rise to bone, muscle, cartilage, fat, and other similar tissues.
Multipotent stem cells are essentially committed to produce specific cell types. They vary from stem cells such as pluripotent ones which can give rise to almost any cell type, or totipotent ones which can give rise to any cell, including the potential to create a complete organism. Pluripotent stem cells actually undergo specialization into multipotent stem cells, and then multipotent stem cells give rise to cells with a specific purpose and function. Multipotent stem cells can be likened to a family-although they do give rise to different cells, the cells themselves are within a certain family and therefore, are closely related.

Stem cells have several uses including:
research – to help us understand the basic biology of how living things work and what happens in different types of cell during disease.
therapy – to replace lost or damaged cells that our bodies can’t replace naturally.

Regenerative medicine is the science of using biologically native (i.e., your own) healing processes in the application of treating pain, injury, or other damage to structures or systems inside the body. In other words, regenerative medicine harnesses your body’s own powers of healing to treat damage to tissues or organs. An alternative treatment to synthetic drugs and surgery, stem cell therapy can help relieve joint pain by reducing inflammation and promoting the growth of new, healthy tissue inside the joint. #celltherapy #stemcells #regenerativemedicine #stemcelltherapy
