Planaria Regenerated Research Paper

Your friend’s dog, Spot, jumped onto a table with a terrarium housing your pet salamander, Lizzie. Unfortunately, the table tipped over and Spot has suffered a head injury which damaged the primary motor cortex. Lizzie lost most of the distal right forelimb in the accident. Please answer the following questions regarding the nervous system and regeneration, in a .docx, .pptx, or .pdf format.

This article studies the ability of regeneration possessed by the planaria. Morgan (1898) observes in different methods how the planaria are cut into smaller pieces, and then he observes the pieces to see if the planaria will regenerate. When the planaria are cut near the head, the pieces do not appear to regenerate, and the pieces cut too small also do not possess the ability to regenerate (Morgan, 1898). Pieces cut from the middle and the end piece of the planaria, however, have shown results of respawning from within the old tissue. When the author tried to fuse two sampled pieces together, he observed that the pieces formed a union (Morgan, 1898). However, the fusion did not last long, and the pieces died long after fusing together (Morgan, 1898). It is likely that the samples were not able to complete the regeneration after the union emerged. I will be able to use this report for my lab report as a reference to the process of taking samples from a live planaria, sampled from the likely

The stem cells that regenerate a frog tail and a salamander limb have very different properties of stem cells. In these animals, each tissue – such as muscle, nerve, or skin – has its own set of stem cells that just make the different types of cells in that particular tissue. In other words, a muscle stem cell cannot make skin and skin stem cells can’t make muscle. These multipotent tissue-specific stem cells are probably very similar to the stem cells in our own bodies that renew or repair tissues such as our skin or muscle. How do these regenerative animals regrow such complex structures? The answer may be closer than we

Introduction: Many model organisms have been used in order to advance human medicine. The primary one being the lab mouse, but there are several other different species that give rise to advancements in human treatment. Planaria and axolotls have been a prominent source of how signaling mechanisms work in order to regenerate parts in eukaryotic organisms. If researchers can figure out how to turn these signaling pathways on in the conserved regeneration part of the human genome, then doctors will likely be able to use this to their advantage. This can be achieved by manipulating human signaling pathways to regenerate tissues within the heart, lungs, nervous system, and even systems with multiple tissue types like the limbs. This is where the study of axolotls comes in.

Caffeine is a wildly use drug in today’s society. Caffeine is a methylated xanthine which acts as a mild central nervous system stimulant (MS & RL, 2001). It is a stimulant which acts upon the central nervous system and increases alertness, wakefulness and restlessness and it increases the release of catecholamine from renal medullar (Fernandez, 2016; Collines, 2007). It is present in many beverages. Caffeine is found in coffee, tea, soft drinks, products containing chocolate (cocoa) and some medication (Collines, 2007). It is used as a cardiac and respiratory stimulant (Collines, 2007).Caffeine is the most frequently ingested pharmacologically active substance in the world (Collines, 2007).

In November of 1998, a group of researchers announced that they had successfully isolated and grown a special kind of cell with the potential to develop into virtually any kind of human tissue. The scientists had made the discovery of embryonic stem cells. The discovery was considered to be an innovative

These cells can grow into many things such as organs, tissues, muscles, or blood. These cells are able to renew themselves through cell division. One of the most unique aspects to these cells are they are able to replenish and repair themselves as long as the person is alive. This can be seen most commonly in red cells of the bone marrow. These cells are continuously repairing and replacing damaged and old cells. Because of stem cells unique ability to renew themselves into new cells, scientist have shown great interest in these cells. Stem cells that are being studied most by scientist are embryotic stem cells, adult stem cells, and induced pluripotent stem

The stem cell of the embryo can divide for long periods of time and still have the ability to produce all cell type in an organism. Their ability to do so is why scientists are trying to find ways to use them to cure or treat diseases. They think that they can programed to repair or replace the disease ridden cells of an infected patient Some diseases that they think can be

Stem cells get their name from the fact that they are basic cells that other cells develop from. They are capable of developing into a wide range of cells. Stem cells could potentially be used to grow new cells to replace the cells that were destroyed or damaged by

Before starting the observations, the planarians had to be cut into sections using a scalpel, in this case, they were cut into three. To make them easier to cut, the were chilled on ice to slow them down.The flatworms were then put into separate labelled petri dishes, where they were then placed in a cool and dark area. After a few days, the worms grew and were easier to observe. From this lab, it can be concluded that planarians will regenerate no matter how they were cut. Wormy and Wormy 2.0, were both trisected transversely and were thought to grow into six new planarians, three coming from each worm, and one of them possessing two heads. The results observed for Wormy fully supported the hypothesis, and the three new planarians had a head,

Many of us have all heard the saying that a “lizard can lose its tail,” and bizarrely enough it will grow back. This was always considered impossible for humans, an idea belonging in the realm of science fiction, but now the regeneration of tissue is an extremely realistic possibility. Despite some opinions, this process does not happen naturally, or take place as cinematically as one might imagine. Over the past decade, there have been major advances in regenerative medicine, commonly known as stem cell research. Stem cells are undifferentiated cells within the body that have the capability to specialize into any tissue. They are most commonly found in cord blood, bone marrow, organ donations, placenta, and embryos . Stem cells are seen by some as a new miracle treatment, encouraging many countries to invest in their research.

They have the ability to self-renew or multiply while maintaining the potential to develop into cells. Such as cells blood, heart, bones, skin, muscles, brain etc. Stem cells have an interesting history that has been somewhat tainted with debate and controversy. In the mid-1800s it was discovered that cells were basically the building blocks of life and that some cells had the ability to produce other cells.

No not everyone’s planaria grew back in the same way. Two groups had full regeneration, seven groups had some regeneration and one group had a mass death. My planaria was in the majority of regeneration. Our result was one new planaria. Some of the things that might have affected the group with the mass death is not having a clean blade to cut the planaria with or there being too much light or their water being too cold because they were near an open window. For the groups that had full regeneration their water temperature was not to warm and not too cold. Their blades could have had remnants of other planaria but the planaria on the blade were healthy. The planaria that only reproduced one planarian could have had a good water temperature

I think I will start off with the Lernaean Hydra’s regrowth abilities. There is a classic greek mythological tale of the greek hero Hercules being sent to kill the hydra in a great battle. When he confronted the beast, the battle began fiercely. Hercules successfully severed some of the hydra’s heads, but soon learnt that they regrew doubled. Before he knew it, the tale says, Hercules was overwhelmed and had to call support from a nephew of his. If one is not careful, the hydra will overwhelm them quickly with its regrowth. After two new heads grow, they too can in turn be cut and turn into yet another
