After doing research on Snopes and other sites, I found that laminin, though it has the 4 'arms' does not always take the shape of a perfect cross, because it bends and twists. Yet, it still has the cross basic shape. And it is still a foundational protein that holds things together.
Snopes and other sites also said that laminin looks like other objects to some people, and not just a cross.
To some people, laminin looks like a sword. OK, that's fine, because the Word of God is related in the Bible to a sword: the sword of the Spirit (Ephesians 6:17). The Bible says that God's Word is sharper than any two-edged sword, piercing even to the division of soul and spirit (Hebrews 4:12).
One Atheist I saw on the Internet posted a sarcastic reply to that video, and said this:
"Y’know, I looked at that laminin protein for a while and I think you’ve got the wrong god. The protein looks a whole lot more like the caduceus wielded by Hermes, God of Travelers, in the way that the serpent-like chains wrap around the staff. While laminin is important for cell structure, DNA is the code that makes us what we are, and its structure is another double-helix, like the caduceus. It really makes you marvel at how the Hermes, the God of Boundaries, extends to the very boundaries of our cells!"

Caduceus
So, to some people, laminin looks like a caduceus, which is a staff with two entwining serpents going up the staff, and wings at the top. Though the caduceus has ties with paganism (used as the symbol of the wand of Hermes, and also as an ancient astrological symbol of commerce), it has also has come to be used as a symbol for medicine. It is similar to the rod of Asclepius, which is a single snake wrapped around a staff, and which also symbolizes the healing arts. The caduceus is often also used as a symbol for medicine or doctors, in place of the rod of Asclepius, which is the usual symbol of medical professions.
Rod of Asclepius

A 1992 survey of American health organisations found that 62% of professional associations used the rod of Asclepius, whereas in commercial organizations, 76% used the caduceus.
According to Greek mythology, Asclepius was said to have learned the art of healing from Chiron. He is customarily represented as a surgeon on the ship Argo. According to some, Asclepius fought alongside the Achaeans in the Trojan War, and cured Philoctetes of his famous snake bite. Asclepius was so skilled in the medical arts that he was reputed to have brought patients back from the dead. For this, he was punished and placed in the heavens as the constellation Ophiuchus (meaning "serpent-bearer"). This constellation lies between Sagittarius and Libra.
In early Christianity, the constellation Ophiuchus was associated with Saint Paul holding the Maltese Viper.
Novidius changed the figure to that of Saint Paul with the Maltese Viper; Caesius gave it as Aaron, whose staff became a serpent, or as Moses, who lifted up the Brazen Serpent in the Wilderness.
The EMS Star of Life, seen on ambulances, features a rod of Asclepius (a blue, six-pointed star, outlined with a white border which features the Rod of Asclepius in the center).
A similar orange star is used for search and rescue personnel and yet another version is used for Wilderness emergency medical technician.
I believe that both the caduceus (2 snakes around a pole with wings at the top) and the rod of Asclepius (1 snake around a pole), both which represent medicine, have their origins from the Bible, when Moses made a staff with a bronze serpent on it, to heal the Israelites.
A similar symbol, Nehushtan, is mentioned in the Bible in Numbers 21:4–9. Attacked by a plague of snakes in the wilderness, Moses holds up a serpent coiled around a staff, both made from bronze, so that the Israelites might recover from the bites. In the Gospel of John, Jesus compared himself to Nehushtan. Jesus taught: "As Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up, that whoever believes in Him should not perish but have eternal life".
Another interpretation is the wooden rod encoiled by a snake to be representative of the Tree of Knowledge. In the Garden of Eden, the serpent/Satan tempted Eve to eat of the apple, which she also gave to Adam, and thereby brought the 'disease of sin' upon the entire human race, which can only be healed by faith and trust in Christ Jesus, the Messiah.
But the point is, whether you think laminin looks like a cross, a sword, a caduceus, or the rod of Asclepius, ALL of those have biblical symbolism and ties, and so the representation of Christianity and God remain! I can only assume that, since God is the One Who created laminin, He made it look that way intentionally, and the fact is, that no matter which of those items you think it looks like, it still does not detract from the fact that there is Christian and biblical symbolism involved, which apparently seems to be intentional evidence that God placed there!
That same Atheist who posted the sarcastic remark mentioned earlier, also said this:
"Then I spent a little more time and discovered the protein called porin. Porins are the proteins that allow for diffusion of molecules across cell membranes. They are the very mechanism by which our cells receive nourishment! Now wouldn’t you know it, but the porin looks just like the triquetta of Celtic paganism. Yet another expression in creation of how the power of three San Francisco witches feed all of us."
OK, so I looked up 'triquetta.' The triquetra (often, triqueta) is a tripartate symbol composed of three interlocked vesica pisces, marking the intersection of three circles. It is most commonly a symbol of the Holy Trinity (Father, son, Holy spirit) used by the Celtic Christian Church, sometimes stylized as three interlaced fish!
Triplicities were common symbols in Celtic myth and legend, one of the possible reasons Christian beliefs were so easily adopted by the Celtic people.
The triqueta makes an ideal Christian symbol. It is a perfect representation of the concept of "three in one" in Christian trinity beliefs, and incorporates another popular Christian symbol, the fish, in its original form of the vesica pisces. It is sometimes enclosed within a circle to emphasize the unity aspect. The triquetra of interlaced fishes is one of the very earliest of Christian symbols, predating the crucifix by hundreds of years.
So, rather than detracting from the idea that God has placed these evidences within our very cells, this Atheist has unwittingly added to it!
Oh, and by the way, that same Atheist that wrote those sarcastic remarks, writes this later on the same page:
"Do you pray for my soul? Are you saddened to know that I will burn in Hell, or do you think God has a special miraculous plan for me? And what of the billions on Earth who do not believe in the salvation through Christ? Do their damned souls make you weep at night?"
