Thanks to a medical hero, Dr. Ernest McCulloch

This Toronto co-discoverer of stem cells is not a household name like Dr. Jonas Salk was after 1955, when he introduced the polio vaccine. 50 years ago, McCulloch and research partner Dr. Jim Till, inadvertently discovered that stem cells exists. Their discovery has since led to treatments and cures for blood cancers like leukemia. In 1960, during the Cold War, they were asked to examine the effects nuclear radiation had on how bone marrow tissue made new blood cells. The non-radiated bone marrow had caused tiny lumps to grow in one group of mice, and it was attributed to the stem cells. Hence, a revolutionary new cancer treatment was conceived.
“They rigorously proved over the course of three or four years that the single cell that gave rise to the spleen colony bumps could self renew and could give rise to all the different types of mature blood cells,” (source: The ... "Their work in the 1960s also paved the way for bone marrow transplantation for cancer patients."

McCulloch wanted to cure leukemia, and his discovery has indeed led to many being cured from it, including this blogger. However, there is much more work to be done to improve survival rates, and reduction in graft versus host disease (gvhd), i.e., the acute and chronic side effect problems, that can be harsh. Stem cell or bone marrow transplants can save lives, allow some to lead normal lives, and cure cancer. However, transplants do not always work, because for one thing, the donor/patient match may not be compatible enough. At other times, they do work but do cause gvhd, which can be life changing.

My gratitude was given to my amazing donor, but now posthumously to Dr. McCulloch who passed away last week at the age of 85. McCulloch and Till's award winning and diligent research has given hope to many who face blood cancers.

You too can give hope and save a life, not just through being a blood donor, but being a stem cell donor. A blood test is taken and the specific (HLA) characteristics and matching criteria are recorded in a registry bank. There could well be a person who needs your exact blood match.

Winter Seens

We're doing very well here on Canada's far East in terms of winter. In the capital city, just one major snowfall so far. Thus far, it seems we are immune to the havoc that winter is causing elsewhere in North America. Hmm, but then again, it is only Jan. 20, and there's a long way to go. There are obvious benefits to our mild winter, from safer driving conditions, to more outside walking, or golfing, opportunities, to the city's reduction in sodium, i.e., less salt use on roads, which means more savings for this old and largest outport. So before going outside for a Jan. walk around the lake, will post a few winter shots taken recently. As they say in Spanish Room on the Burin Peninsula, adios for now.

Birth of "this" universe

On ground Hubble Jr. was able to capture early clusters of exploding unstable stars, normally called red giants. Hubble was able to zoom to a young universe at just 4.5 million years old, when cosmic wind forces from the initial big bang created instability among emerging star formations. What we see are the remnants, the shattered dreams of potential shining stars, which still showed us the stuff they are made of. Yet despite their brevity, they left an impression from just an instance of life, that rekindles an appreciation for the value of short lives, to contribute to life's dreams, potential, beauty of life and nature.

Who knows what we have yet to discover about the universe and ourselves - the sky's the limit.
