Background

R-Spondin 1, also known as cysteine-rich and single thrombospondin domain containing protein 3 (Cristin 3) , is a 27kDa secreted protein that shares ~40% amino acid (aa) identity with three other R-Spondin family members (1, 2) . All R-Spondins regulate Wnt/beta-Catenin signaling but have distinct expression patterns. R-Spondin 1 competes with the Wnt antagonist DKK-1 for binding to the Wnt co-receptors, Kremen and LRP-6, reducing their DKK-1-mediated internalization. However, reports are mixed on whether R-Spondin 1 binds LRP-6 directly. R-Spondin 1 is expressed in early development at the roof plate boundary and is thought to contribute to dorsal neural tube development. I Postnatally, R-Spondin 1 is expressed by neuroendocrine cells in the intestine, adrenal gland and pancreas, and by epithelia in kidney and prostate (9) . Injection of recombinant R-Spondin 1 in mice causes activation of beta-catenin and proliferation of intestinal crypt epithelial cells, and ameliorates experimental colitis. Mouse R-Spondin 1 shares 98%, 94%, 94%, 93%, 92% and 88% aa identity with rat, human, horse, cow, goat and dog RSPO-1, respectively, within aa 21-209. Recombinant Mouse R-Spondin 1 is a single non-glycosylated polypeptide chain containing 189 amino acids

Miracle. It's a miracle.
Size: Standard (Medium)
After years and years of searching for a comfortable pillow, I've finally found it! I was hesitant to try latex because I have severe sensory issues and thought it would be weird, smelly and maybe noisy. I really couldn't envision how it would work. The reality is a perfectly bouncy soft pillow that supports your head and neck at just the right height and has immediate bounce back so that when you turn in the night you don't have to waste hours or even minutes fluffing plumping positioning or any other nonsense... You just flip yourself over and go back to sleep. It's a friggin miracle!!! There is a very faint though tolerable and fading scent of balloons. Not too bad for me, but might be annoying to some. Overall, thank goodness I bought this pillow. I'm tempted to replace all my pillows with latex ones but... I don't really need any other pillows now! Maybe I will just so I have spares or something. Granted, it's only been about a week but I expect it to be fairly durable and hold it's quality for quite a while. So thrilled! Just so happy with this purchase! Ten stars, ten hearts!

Very Firm Latex Medium, Appears Well-made
Size: Standard (Medium)
I love latex pillows, used them for decades. Then I got led astray! My neck reminded me I need firm, but soft and bouncy. This pillow is surprisingly firm for a medium. So think twice before ordering firm.

Comfortable but smaller than a standard pillow.
Size: Standard (Medium)
The pillow is bit smaller than standard length wise. It takes a while for the smell to go away. Very comfortable pillow.

Remarkable and impressive pillow
Size: Standard (Medium)
The pillow came quickly and was what was expected. After 6 months of chronic neck pain, one night on this pillow has made a world of difference. Please buy one of these if you are on the fence. They are wonderful. Highly recommend.
