The present venture I’m engaged on in OUMERE Labs is to survey the adjustments in pores and skin on the mobile stage. The experiment I’m conducting now’s to match pores and skin that has been present process every day liquid exfoliation with the No. 9 exfoliant, and to match it to pores and skin that’s untreated.

I imagine that after one week, there will likely be seen variations to the pores and skin from the experimental group that can spotlight the advantages of exfoliating the pores and skin each day with the No. 9. 

The present experiment is on day 5 of seven, and on the seventh day I’ll start the histological strategies wanted to then view the specimens below the scope and get my ultimate outcomes. 

This primary spherical of the experiment is usually for me to high-quality tune my embedding strategies as a result of so much must be discovered first earlier than going into a big scale run of the examine. As soon as I’m able to use these present specimens to hone in on precisely the best way to keep on the embedding, fixation, staining and different histological strategies I can repeat the experiment with a big pattern measurement.

Beneath is an summary of the examine that will likely be carried out in OUMERE Labs for the subsequent few months:


Supplies & Strategies

Human pores and skin samples obtained from reside human tissue will likely be used for this examine. The samples are obtained from Genoskin, who retrieves donated pores and skin from human sufferers. 

Present pattern profile:

Intercourse: F

Age: 45 years previous

Origin: Hispanic

Pores and skin kind: 2

BMI: 32.4

Anatomical web site: Stomach

Surgical procedure date: 09/07/2022


The pores and skin samples are biopsied into 11mm sections and individually positioned into wells in a 12 effectively plate. As soon as the effectively plate is obtained into the lab, development medium is added to the plates as soon as per day for 7 days to maintain the pores and skin alive.

The specimens are incubated in a CO2 incubator at 37C per the producers suggestions.

Since I’m simply utilizing this primary spherical to find out my embedding strategies, I’m simply utilizing one effectively for the experimental, and one for the management. 

Experimental protocol: Daily at 10:00 AM the experimental effectively is swabbed with a cotton swab containing the No. 9 exfoliant. 

Management protocol: Daily at 10:00 AM the management effectively is swabbed with a cotton swab containing distilled water.



The specimens are then put again into the incubator for twenty-four hours.


Subsequent steps

As soon as the experiment is accomplished on Friday, I’m going to observe typical electron microscopy strategies to embed the specimens though I’m not going to have a look at these specimens below the EM. The explanation for utilizing EM strategies is as a result of I imagine the fixative and sectioning steps concerned will give me a greater view of the samples below the sunshine microscope than if I have been to make use of widespread tissue prep strategies . Akin to paraffin embedding and trichome staining together with sectioning below a microtome (versus the ultratome I will likely be utilizing right here).

I feel for this pattern fixation with picric acid adopted with a drawn out dehydration then embedding in epoxy resin will give an fascinating look of the tissue samples above, so I’m going to present it a strive. The tissue prep will take about one week, then I can part the samples, stain it and have a look at it below the sunshine microscope. 

If all the above goes in line with plan, I’ll then repeat the above experiment with 11 experimental wells, and 1 management. 



I predict for this experiment that there will likely be a visual change within the thickness of the experimental pattern. This alteration will likely be as a result of upregulation of pores and skin extracellular matrix proteins.
